Ultimate Wordpress Caching (not for the non-programmers)

[jarrod1937]

Well, I believe most wordpress installs allow you post a comment without logging in, which is why you'd need the cache invalidation code within the wordpress comment submission code. Though, if you rely on an external comment system, loaded via ajax like disqus, then that is a non-issue because the cache will not include the comments.
In general though, I think someone could set this type of system up and make use of it and w3 total cache. That way, you can set a lower cache time, and when the cache has expired, the initial load time is less still than without the w3 plugin.
Eitherway, the system as-is is good for me. If I do add a comment system, it will probably be something like disqus, and with the system my site is quite zippy... aside from the fact that the host has keep-alive's disabled, but that's another issue.
