w3 Total Cache version: 0.9.2.8 with WP3.5.0
We are running a large traffic website on AWS (several Amazon instances), we had to disable disk caching (due to the various server instances and bugs related to that) and choose memecaching.
However, memecaching disabled fragment caching for certain dynamic parts for the site e.g. ads, conditional sidebars etc. As we found the page and WordPress PHP logic is baked into the cache before it can even execute any wp functions.
In the past we solved this for PHP include fragments with an function_exists check. At least that fixed it for us in PHP includes. Now that does not work either.
Is it possible to use the "mfunc" tags for fragment caching at all (when using memecaching)?
We are urgently looking for a solution, is there any trick to this?
Many thanks for any hints.
