[Plugin: W3 Total Cache] W3TC fragment cache for wp/bp admin bar

Well that’s not an easy thing to do, definitivly.

1 / I tried to fragment the whole header, and css disappeared.
2 / I tried to wp_head and bp_head functions in header.php, it crashed the site, (blank page).
2 / I also tried to fragment comments part, it crashed too.

Maybe fragment is not the goog way, i don’t know ??

3 / I tried to fragment sidebar, sidebar disapeared… So i spent hours on this, i searched in google, and wp support forums, but topics and fragment cache infos are weak and lonely, and that’s a problem cause wp/bpress installations really need cache. It would be a nice idea to improve this, cause this is a major need for non statics websites.

And then to add something to w3tc like “force to include pages to cache” even for logged in users, or by user roles (admin/followers), cause it’s that kind of logic a cms/community wp needs.

Then why don’t go further and force to cache parts of a page (i mean post lists elements and else), because the opposite : “not caching with mfunc” is just strangely added to the plugin.

The fragment functions only works with non WP functions and with opcode/memcached cache engines. You’ll need to experiment and check out WP Transients API to get it work as you want.
