I did a bit of digging, I would suggest that you become familiar with the structure of the code here, I use zend studio but any decent text editor should have a search feature.

What I found was that the cache is being done by the simplepie.php under concrete/libraries/3rdparty/simplepie.php

This is a huge file and I am in the middle of doing something so I don't want to get too distracted, but you could maybe try disabling cache by editing cache duration on or around line 472. It is currently set to cache for 3600 seconds which is an hour. This is PROBABLY where your problem is.

the code is this:



Try editing that file with a duration of something that won't get you banned, maybe every 2 minutes or something like that, or 120 intead of 3600.

If your site isn't visited often you could even make it 30 seconds or something like that.

Now if you want you can probably recreate the tree structure outside of the concrete directory and keep the simplepie there unaltered, but i think a simple fix as long as you know where you made the change couldn't hurt.

This seems to work-- thanks for the tip!
