It would be great if W3TC could create a different version of disk enhanced files for ajax requests. On the server where is original cache html file is stored a new folder could be added (maybe named ajax?) which will include the html file of a particular ajax request. So whenever W3TC will detect something like:
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
....
}
create the ajax version of this particular page.
Why would this be useful? On my page I have 2 versions of each post, a regular post and the same post on ajax which requests less data. On the ajax request the header and the footer are excluded so less data is being requested.
Thanks for your efforts and the marvelous plugin!!
