Using mod_jw_srfr-v3.0_j2.5-3.0 I seem to have found a bug in the caching code.
If I have two or more modules with rss feed urls like

www.ramblers.co.uk/walksfinder/walksfeed.php?group=DE02&days=Sunday
www.ramblers.co.uk/walksfinder/walksfeed.php?group=DE02

i.e. with different options on the base url
then all the modules display the same information.

Looking at the cache there is only one cache file for
ramblers_co_uk_walksfinder_walksfeed_php.cache

Hi,

I have the same problem. 

Look at forum.joomlaworks.net/simple-rss-feed-reader-%28module%29/rss-feed-cache-issue/

I have posted that on the April 22 but had no response or acknowledgement from the developers at all

:(
