CacheFu does not cache "parts" of a page. If it's just parts that are
being cached, you probably should look elsewhere for the culprit. I
believe contentwellportlets are viewlets so it's probably not a
RAMCache unless you're doing some sort of encapsulation using a
RAMCacheable container. I don't believe that contentwellportlets
contains any internal caching code.
Assuming we are truly talking about caching the *whole* page and not
just pieces of the page, then CacheFu could indeed be the culprit.
Look at the response headers (use the Firefox LiveHTTPHeaders
extension) to find out what CacheFu rules and headers are being
applied. Once you know how the caching is being done, you often have
several options. Fix the matching rule so it no longer matches your
item. Or make a copy of the matching rule (or create a new rule from
scratch), customize it to match only the item you want to exclude and
apply a less aggressive header set to it.
FYI, one trick to get some caching speed even from pages with some
dynamic elements is to encapsulate the dynamic bits inside a separate
javascript call from the page. Then you can aggressively cache the
page html while the javascript-generated portions are non-cached.
