 * I am using WP Super Cache on a multisite 3.0.1 installation. For some reason,
   many of the Super Cached RSS feed files are not expiring properly.
 * For example, a custom feed URL such as [http://example.com/feed/?taxonomy=test&term=test-term](http://example.com/feed/?taxonomy=test&term=test-term)
 * That feed gets cached by WP Super Cache on the first request, but it does not
   expire as new posts are published, and it does not even expire after my time 
   limit setting of 230 seconds.
 * Is there something in my WP Super Cache configuration that may be causing this,
   or could this be a bug with WP Super Cache?
 * Thanks for your help,
    Dave

 * Supercache shouldn’t even cache that as it has a non empty GET. When I try a 
   similar url I get a 404 on my blog.
 * Can you paste the output of the debug log into a pastebin and post the url here
   when you request that url as an anonymous user?

 * Here is a sample feed URL: [http://insidescoopsf.sfgate.com/feed/?taxonomy=niche-site&term=ns-main-well](http://insidescoopsf.sfgate.com/feed/?taxonomy=niche-site&term=ns-main-well)
 * Here is a pastebin of the super cache debug log: [http://pastebin.com/T7KJHyu7](http://pastebin.com/T7KJHyu7)
 * I see what you mean about how Super Cache is not handling this feed. I suppose
   where I’m getting confused is when I set the timeout to something like 10 seconds,
   I would expect that WP Cache file that is being served up to regenerate if I 
   make another request to it after 10 seconds.
 * Is this the expected behavior, or am I missing something else in my configuration
   of the WP Super Cache plugin?
 * Thanks,

 * First thing you should do is upgrade WP Super Cache. I checked the headers on
   that url and it shows a header that hasn’t been used since 0.9.9.3.
 * Upgrading may help.

 * I noticed that the latest version is designed to be run within the /plugins folder.
   Will it still work in the mu-plugins folder? I run 1500 blogs on this platform,
   so I want to make sure that I don’t break the caching mechanism when I do the
   upgrade.

 * Yeah, it will but it’s more convenient having it in plugins as you’ll get notifications
   about new versions.
