Question on removing cache based on url.

[John Villa <john.joe.villa@xxxxxxxxx>]

Hello,
I am currently trying to purge objects that are older than 2 minutes.  
The particular site is amazon. It does not appear to be working with  
my configuration because I tried this on a site with a few words of  
text and the object that it created was not purged. Here is my config  
line:
refresh_pattern -i .*\.amazon\.com      1       20%     2
Thank You,
-John
