There are two caches here:
- portletcache takes care of caching the portlet object in memory.
- diskcache takes care of caching the URL to avoid thrashing other servers.
You have removed memory cache for this portlet, but not disk cache.
So your url will be updated once an hour when DiskCacheDaemon runs. The only URLs that
the current
DiskCache does not cache are "localhost", "yourhostname" and "file:/" urls.
I have a prototype of the new cache, but I'm flooded with other work, and it is not
even functional now.
Once think we will have there is being able to specify regular-expression cacheability
of URLs.
I'll think of a quick workaroud for specifying non cacheable URLs with
the current codebase.
