Hate to respond to myself, but I wanted to add more info..
In a well duh moment I ran find and found objects going back to July.
find /cache -type f -mtime +30 -exec ls {} \;
If my headers from my web servers are set to expire in 2 weeks:
Cache-Control: max-age=1728000
Connection: close
Date: Wed, 19 Sep 2007 00:38:51 GMT
Accept-Ranges: bytes
ETag: "1155193587"
Server: lighttpd
Content-Length: 68424
Content-Type: image/jpeg
Expires: Tue, 09 Oct 2007 00:38:51 GMT
Last-Modified: Mon, 17 Sep 2007 20:03:00 GMT
Client-Date: Wed, 19 Sep 2007 00:38:51 GMT
Client-Response-Num: 1
How did my expires make it keep files for so long and why did my new ones not
start a purge?
Thanks
Nicole
