Page caching

[Miguel A Paraz <mp...@gmail.com>]

Hi,
I'm working on the UI for Planet group selection. I notice though,
that query parameters don't force a cache refresh. I added a ?group=
parameter to select the group for PlanetAction, which passes it
through an attribute to ./planet/planet.jsp.

I'm not familiar with the caching system configuration - some hints please? :)

Thanks. I'll start by reading through the caching code.

I'm also looking at user-defined aggregations of blogs - the admin
adds or approves feeds, then users publish their own groups.

actually, it's not so much a matter of cache refreshing as it is about 
how the cache keys are created.  the cache keys are very specific and do 
not support arbitrary query params, so your problem is that the cache 
simply uses the same key for all of your /planet.do?group=XXX urls.  the 
same issue exists for the /main.do page and Dave, Matt S., and I were 
talking a bit about it on friday because jRoller uses some modifications 
to the /main.do page.

there is no easy solution to the issue right now, you will either have 
to disable the cache or make some slight changes to the code which 
constructs the cache keys for the planet cache.  i'll be looking at some 
ways to make that easier to configure, but there is no ETA on new code.
