Wow. I guess I'm the first one to comment on your new plugin. Let me first state that I completely wiped WP-Cache in favor of your plugin. I love some of the extra features and to be honest; developement of WP-Cache was dead a long time ago and I rather support a developer who's willing to pick things up again.

Everything is running smoothly with 1BlogCacher, but I just can't seem to get the new (2.0) dynamic code to work. This used to work perfectly with WP-Cache, but with 1 Blog Cacher I just get a completely white page (no source code either). I used this function call(s):

[!--mclude /wp-content/plugins/rthanks.php--]
<!-- -->
[!--/mclude--]
[!--mfunc refer_thanks() --]
<!-- -->
[!--/mfunc--]

This is the plugin's url: rThanks.

Why do I get white pages (no output) when I include this in single.php? Did I misunderstood the compatability?

Oh! I have all the default options in advanced_cache.php, including:

define(«OBC_LOOK_FOR_DYNAMIC_CODE»,true);

Thanks for looking into this!

Hi Javier,

1. Did you mean I should redownload 1Blog Cacher? (meaning: you fixed this in v2.0)
2. Will check on the missing end tag, but it didn't work with another plugin either.

Performance is excellent btw!

Thanks Javier. The rthanks() plugin now works again
I seem to have trouble with another plugin (Who Sees Ads), but I already had this problem with WP-Cache. It has to do something with parameter calls. Dynamic functions somehow only seem to function when there's nothing between the parenthesis ().

Works:
[-?-php rthanks() -?-]
Doesn't work:
[-?-php wp_ozh_wsa('mybanner') -?-]

Hi,

sounds like an interesting plugin and wp-cache2 replacement.. does someone made some performance compares against wp-cache2? It seems, that this plugin is more often updated and the better solution for me.

thanks for this plugin, great work in my opinion.

hello again,

since i installed blog cacher the semmelstatz plugin isn`t logging refferers.. hits work and visits (i think) but referers not.

Hi Javier,

if i use the dynamic functions (mfunc e.g. like ) the browser loads an blank, white page. i tried both, php include and func, both gave me a white page.. hm, i don`t care about a lot and 1 blog cacher is sure the better choice than wp-cache since version 2.0, and there are apache logs, sure, to get a statistic overview; but i like semmelstatz plugin, maybe i find a way to get my refferes back (hits are working). thanks for you fast reply

have a nice day

Hi, i'm using right now wp-cache and it's a great plugin.

But, I want to know what is the difference between this plugin (i blog cacher) and wp-cache.
It's a good idea to switch to «1 blog cacher» from wp-cache ?

thanks for your answer.

Hi there,
I've got the following error:
----------------------------------------------------------------------------
Installation error

The file - /www/htdocs/v101/wp-content/advanced-cache.php - is incorrect or you haven't added the code define('WP_CACHE', true); to the file /www/htdocs/v101/wp-config.php

----------------------------------------------------------------------------

I've uploaded the file in the correct folder (wp-content) and I added the line to the wp-config.php.

Any idea how to get the plugin working? I've got WP 2.3.1

..and now tested in 2.3 and 2.4 trunk and seems to work

I was wondering. Is the user experience when they view the site identical (apart from being faster), or do things work differently?

@Javier García,
you are my hero! I've now added this line directly under the mySQL-Settings, now it works perfect. Thank you.

Hi,

a little bug report along with a fix: The plugin doesn't work on sites with SSL support. When the plugin is installed and run at https://www.example.com/, it tries to redirect to https://www.example.com/. In some cases, this will undermine security, when the non-secured site is displayed instead of the secured one. in other cases, when the http site redirects to the https version, the plugin can cause an infinite loop.

The fix is quite easy:
In advanced-cache.php, add a line define("OBC_SCHEME", 'https'); to the settings. Then replace the hardcoded references to "http://whatever" with OBC_SCHEME.''://whatever". Works fine in a project of mine.

Of course, the default value for OBC_SCHEME should be 'http'.

By the way, another option would be to determine the scheme automatically, for example as in wp-login.php.

Hi, me once more. As I have a working copy of the site on a non-SSLed server, I had to find a dynamic definition of OBC_SCHEME. Here it is (inspired by wp-login.php):

define("OBC_SCHEME", (isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on' ? 'https' : 'http'));

Sorry to nag again, but there is yet another issue with your plugin: You've choosen the CC-BY-NC-SA license, which conflicts with the GPL license of WordPress, as it allows no commercial usage (commercial usage is not bad, as long as people share the modified code!). This makes many usage screnarios of your plugin very problematic; in fact, no company website would be allowed to use your plugin. Your CC license is also problematic as your plugin is based on WP Cache, which is released under the GPL, and you cannot put the code under a more restrictive license.

Therefore I'm asking you kindly to consider releasing the next version of your plugin under the GNU GPL.

Much smoother cache plugin than WP-Cache! Thank you.

However, I am having a major problem: my comments will not refresh. In other words, new comments don't show up in the page after being submitted. They show as being received in the Comments portion of the Dashboard, but otherwise they don't show on the cached page being retrieved.

I use Brian's Threaded Comments and Spam Karma 2. In the past, those did not play nicely with WP-Cache. However, Spam Karma 2 includes a plugin that forces it to work with WP-Cache correctly. Enabled or disabling it, though, did not fix the issue here. Brian's Threaded Comments also had a workaround with WP-Cache.

Any ideas? Your plugin works great, but if I can't get my comments to show, I'll have to disable it.

Hi,

My blog is low commented since it's truly personal and very few friends of mine come to check it. Do you think that it is reasonable to use caching?

I'm using a plugin to display a picture on Picasa randomly. If I installed caching plugin would it work as normal?

One more question concerning the compression. As I understand, the server will zip the files and send them upon the request. User end will unzip it and show the result on the browse. These steps surely consume some time (and server load as well). I have no idea about this time scale, is there any case that this time is greater than one we save due to the small files?

I get this error after install:

1 Blog Cacher
Installation error

The file - c:/Websites/digitalpickles115/thebitbag.com/wp-content/advanced-cache.php - is incorrect or you haven't added the code define('WP_CACHE', true); to the file c:/Websites/digitalpickles115/thebitbag.com/wp-config.php

I added the define line and still get the error. At first I thought it had to do with 2.3.2 so I put it on a 2.3.1 install then upgraded the install and the plugin still worked on that install which is another site. I've tried everything and can't get it to work. I've disabled ALL plugins and still can't get it to work. PLEASE HELP ME as I NEED to have caching for when my site gets dugg again.

Thank you so much!

Great idea, but I'm having the same problem as when I tried WP-Cache. That is, using mclude and mfunc to NOT cache areas of code I want to keep dynamic. In my case, I have a randomized blogroll and real-time visitor stats (using wp_meta()). I can't seem to get those areas to stay dynamic.

Well that was painless to install! Thanks!

Curious - wp-cache and super-cache don't play well with Bad Behavior. Does Blog Cacher?

Well Bad Behavior is still blocking access attempts (as it should) so they seem to work just fine together.

Loving Blog Catcher! Nice work!!

Have you used this plugin with Alex King's Popularity Contest plugin?

Hi. I am using Wp Super Cache, which seems to have some of the same features as your plugin. Can you suggest what is the difference between the two?

I haven't had the chance to take a look onto the code of the Wp Super Cache plugin, so I couldn't really tell. But I'd say 1 Blog Cacher has better http headers support (this is better performance, as it saves processing and bandwidth).

I use Search Unleashed to highlight search terms. On it's website, (http://urbangiraffe.com/plugins/search-unleashed/), the author remarks about a change to the wp-cache-config.php file that has to be updated to avoid caching search terms. Would a similar change be necessary with 1 blog cacher? If so, to what file should I add the code?

You'll probably want to avoid caching the search files, read the documentation on that plugin.

It has documentation related to wp-cache. It gives the additional code to add to wp-cache-config.php. What is the equivalent file for 1 blog cacher, so I can try that code in that file?

There is no equivalent file as this plugin works differently, but as long as it only contains one plugin file (1blogcacher2.0.php), you should try on that in order to avoid highlighted words caching.

I found your site because I was checking out the source code on a blog. I just thought that you might like to know that that blog is Ebay's corporate blog: ebayinkblog.com

Congratulations!
And I think I'm going to love this plugin. It seems to support more plugins than WP-C or WP-S-C.

Thank you! Glad to know that :P.

seems like a great plugin, thanks so much. an obvious thing that is missing is an option to temporarily disable cache, like it's possible from within the classic wp-cache. i hope this functionality will be added in the future releases. in general, the web interface looks limited at this time. can't wait to see this one advancing. thanks.

Just disable the plugin, it's one click; that option is completely unnecessary. I don't know what you mean by limited but the plugin is the more customizable caching plugin out there.

Javier, where could i read about about 'dynamic code' support and syntax? what i really need to achieve is being able to use this plugin with an internal stats package like statpress. i know there're external solutions, but i need statpress or its analog to work. obviously statpress is not executed when a cached page is served.

if only i could make it work somehow, that'd make my life compelte :).

thanks again for this plugin, i'm loving it more and more the more i observe its behavior.

It's compatible with Staticze Reloaded. From their FAQ:

There are two ways to do this, you can have functions that say dynamic or include entire other files. To have a dynamic function in the cached PHP page use this syntax around the function:

< ?php function_name('parameter', 'another_parameter') ?>
`

The HTML comments around the mirrored PHP allow it to be executed in the static page. To include another file try this:

< ?php include_once(ABSPATH . 'file.php'); ?>
`

That will include file.php under the ABSPATH directory, which is the same as where your wp-config.php file is located.

O melhor plugin cache do mundo.
very good plugin world

Great plugin! With 1blogcacher I just managed to have dynamic code includes working, while I couldn't (don't-know-why) using wp-cache. Definitely better than that!

Sadly I had to temporarily turn back to wp-cache.
Comments section of the page does not work properly for logged-in users: I am admin but I see the page as a normal user, including the contact form (using Cforms now).

Tried to set

define(«OBC_CACHE_USERS»,0);
define(«OBC_CACHE_COMMENTERS»,0);

but no success.

This is how it's should look like (wp-cache ON)

and this is how it looks with 1blog cacher

Please, update to the newest version.

I downloaded it from wordpress.org plugin directory, it was v. 2.0.2

v. 2.0.4 from here is perfect instead, thanks! =)

Thanks.

Hello, great script, thanks. Much more easy than super cache. Hoiwever, I want to keep an include to a «online users» script and a external counter dynamic, I don´t know how, can you explain better?

So how does the browser cache work? I read somewhere that you send expire headers. But when I enabled it, and the hour passed (the expiration for the cached file), it still served the contents of the browser's cache. Needless to say, I don't want to enable this and then have all my visitors seeing stale pages that are days, weeks or months old until they clear their caches (or the browser does it automatically). Is there something I'm missing here?

John, HTTP headers are used so the plugin checks that the content hasn't changed. If content hasn't changed, the browser copy will be used (it's faster).

Thanks a lot. I prefer this one over WP Super Cache.

Hello ,
I came across your plugin while I was surfing » On how to fix wp super cache » had problems with it just like others
It seems that this plugin should take the top position in wordpress plugins directory instead of wp-super-cache
Friend I have a question since I`ve just started using it . Does it cache advertisments as well.
I ask so because I see same advertisements on the pages
Pls do not mind my dumb question I am a beginner in this wordpress world

The plugin caches all that is cacheable, this is, the code returned by your blog (unless you use dynamic code, see comments above). So it depends how you display your ads (javascripts like AdSense won't be cached).

Is there anyway to configure it so that users can see that their comment is awating moderation?

That's a theme feature, the plugin just caches what the theme returns. Most themes warn that a comment is awaiting moderation.

When I leave a comment in my blog with the 1 Blog Cacher activated, I don't see the moderation message. I can only see the moderation message when I deactivate the plugin.

Hello Friend ,
I am using your great plugin on my website. It is working absolutely fine no issues with it.
I am using a plugin called tdomf plugin from http://www.thedeadone.net it allows unregistered users to send in posts.
I have a form on my all pages at http://www.liarworld.com through which visitors send in their posts.
So now when I use this plugin of yours it caches that form and its function.
Is there a way through which I could disable the caching of the form and its functionality like preview and send function on all the pages and cache the remaining portion of the pages.
Your help would be highly appreciated.
Thanking you in advance.
Jitender Sharma

Hello Jitender,

You can use dynamic code (read comments above).

This plugin is awesome. Thanks Javier for your effort

hello,
I'm a little confused.
when I use ctrl+F5 to refresh, I can always find the date changes.
Dose that mean every time it is loaded from database?

Ctrl+F5 bypass the cache and asks for a fresh version of the page. On features:

«Browser super-reload (Ctrl+F5) avoids cached urls.»

That's the expected behaviour with caches.

I had another try.
I cleaned up all cached files for my browser, IE and firefox.
And then every time, I find new timestamp in web page source.

So, dose that mean, a new visiter will always see a new page?

The timestamp is created on the run, it doesn't mean that a cached version of the page existed.

Hello, nice plugin! It realy let the site speedy!

However, I get this errors when I update or publish a post:

Warning: Invalid argument supplied for foreach() in /home/s61763/public_html/wp-content/plugins/1blogcacher2.0.php on line 70

Warning: Invalid argument supplied for foreach() in /home/s61763/public_html/wp-content/plugins/1blogcacher2.0.php on line 70

Warning: Cannot modify header information - headers already sent by (output started at /home/s61763/public_html/wp-content/plugins/1blogcacher2.0.php:70) in /home/s61763/public_html/wp-includes/pluggable.php on line 850

Didn't find a solution on the web. What does it mean?

Thanks!

Your file pluggable.php probably has some spaces or blank lines outside the PHP tags, initilizing the output and hence invalidating the headers sent by the plugin.

Hi Javier! Thanks for helping me.

I have tried to replace the pluggable.php by the original of WorPress unsuccessfully. The same erro ocurs. What a strange thing! I have never made any changes in pluggable.php.

Don't know what to do anymore.

Anyways, thanks a lot!

Hi there! I'm here for feedbackyou all.

My problema above was that my hosting service limits many important funciont that 1 blog cacher needs to work. One of them is that php runs in safe mode. Another one is that they don't permit to give 777 or 775 access to wp-cache folder. That may be surely causing my problems.

See y'a!

Hi!
Many thanks for this plugin. I giving it a try, and it seems to work fine. It's very fast.
However, I have run a few tests with apache bench to compare it to Super Cache, and got (average results):

Blog cacher: ~524 req/sec
Super Cache: ~1300 req/sec

with a simple «ab -n 1000 vitobotta.com/» (where vitobotta.com is the blog, not ready yet, I am working on, and with all plugins deactivated apart from the caching)

I haven't tried with the concurrency though.

Am I missing something? I followed your simple instructions and your plugin seems to be working great, still I cannot explain this huge difference (> 2x).

Many thanks in advance for any clarification.
Vito

Thu plugin works better with «real» petitions. For instance «ab» doesn't handle well HTTP headers, and the plugin makes extensive use of them («not modified», etags, etc.). It also works better with petitions to different urls, not the same one (the directory structure improves the cache retrieval).

This plugin is phenomenal. It's an a masterpiece. Works like a charm.
I've been fighting with these other WP-SuperCache and Hyper Cache plugins for 2 days now..
I've just tried 1BlogCatcher and it's extraordinary!
Thank you so much for this great plugin. There is no donate button, but I am gonna click Adsense ads everyday here

Actually there's a donation button on the right sidebar...

Hi Javier,

many thanks for your reply. Is there any sort of benchmark I could use to reliably see which one is faster for my blog?
Thanks

A real site with real users, and check the performance...

Oh, sorry. I didn't see that!

Btw I have this problem.

http://mysite.com works all right.

http://www.mysite.com <-- Gives «Error establishing a database connection»

Do you know how to fix this?

The plugin doesn't establish a database connection, it just caches what WordPress returns.

But when I deactivate it it works both ways with «www» and without.
However when I activate it works only without «www»

I don't know, you should make a little debugging and check what url is really the plugin accessing.

How to do that? :S
perhaps something to do with .htaccess?

No, if you don't know PHP it's better that you don't touch anything. In any case without more information I can't really tell what's happening.

Oh and btw... Why does it show 2 diffrent loaded times, when I use 2 diffrent browsers...? Chrome diffrent than Firefox... Shouldn't it be the same file? (with same loaded time)

Probably cookies (from commenter, admin...) are different.

Something is not right It sometimes caches «Error destablishing a database connection»... And doesn't want to refresh..

Those pages are returned by WordPress, not the plugin. The plugin simply caches them, in order to avoid this you can tweak the advanced-cache.php to filter ot that kind of pages.

Half of my posts are like that.
Could you tell me what should I add to advanced-cache.php?

Around line 205 you can see how the plugin determines when not to cache a page ($no_cache = true).

Is it possible to use 1blogcacher with wp-postviews?

I don't know exactly how that plugin works, but most likely by caching the pages you will reduce the post count in the stats.
