Caching plugins are very challenging to disable because on top of normal plugin functionality they tend to: created extra drop-in files set caching constants bypass PHP completely with .htaccess While it’s not impossible to mangle specific plugin into submission, it’s flaky. More reliable to explicitly disable it in dev and keep. Note that implicitly stopping … Read more
This can be accomplished with fragment caching feature that W3TC has. Had been asked/answered couple times.
Got the solution. Instead of using the CDN exclusion list, I use the plugin (W3 Total Cache) “Page Cache” option. Once logged in as the administrator, go to W3 Total Cache settings (a tab called “Performance”). Navigate to “Page Cache” and then to the field named “Never cache the following pages:” Finally enter the name … Read more
Couple different things going on here, but my two cents: 1) Philosophically: if a file may be modified somehow in any of its remote deployment contexts, don’t keep it in the repo. Since W3TC keeps its settings in a flat file (and that flat file is updated every time you go into the W3TC settings … Read more
W3 Total Cache is a very advanced plugin that has built in ways to handle almost any situation. To exclude a page from being cached use one of the following commands below: define(‘DONOTCACHEPAGE’, true); Disables page caching for a given page. define(‘DONOTCACHEDB’, true); Disables database caching for given page. define(‘DONOTMINIFY’, true); Disables minify for a … Read more
As the commenters have alluded to, this is a “feature” of using cookies. Changes to cookies are only enacted on the next page refresh. You could try adding an extra page refresh (which will make the users browser page flash) or you could add some JavaScript to destroy the cookie dynamically.
The following script takes the url that was asked from the client. It checks whether there is a fresh version of a static HTML page on the cache and if yes, it servers that. If the file does not exist at all or the it is expired(I check its modification date) then the request is … Read more
Short answer: You can’t. Getting W3 Total Cache to talk to a non-WP call in manor listed above isn’t (easily) possible. I completely agree with @allenericr comments. The Transients API is very straight forward and quite simple to implement. In addition, @allenericr, comment on using admin-ajax.php is also spot on. It’s not sure it’s best … Read more
Create a file specifically for W3 Total Cache configuration for your site, in a location Nginx/PHP-FPM can write to. Include this file in your site’s Nginx server configuration. Then on the General Settings page, under Miscellaneous provide the full path to this file in the “Nginx server configuration file path” field. W3TC will then know … Read more
From the source: Here (source) is the mfunc part in the 0.9.2.9 version of the W3TC plugin where the regular expression is: $buffer = preg_replace_callback(‘~<!–\s*mfunc\s*’ . W3TC_DYNAMIC_SECURITY . ‘(.*)–>(.*)<!–\s*/mfunc\s*’ . W3TC_DYNAMIC_SECURITY . ‘\s*–>~Uis’, array( &$this, ‘_parse_dynamic_mfunc’ ), $buffer); From this it looks like the setup should be <!– mfunc W3TC_DYNAMIC_SECURITY code1–> code2 <!– /mfunc W3TC_DYNAMIC_SECURITY … Read more
