RE: [squid-users] Purge utils

As far as I am aware (and I may be wrong) Squid's purge method does not have
the ability to do "fuzzy" purging. If you want to purge
http://my.domain.com/page2.html from the cache, then you have to run
"squidclient -m PURGE http://my.domain.com/page2.html". You can't purge all
the cached pages from a site in one fell swoop using the default tools.

Thanks Emilio, I had my acl wrong but after I corrected it I see
TCP_MISS:NONE in the access log when I do the following
# squidclient -m PURGE http://my.domain.com
HTTP/1.0 404 Not Found
Server: squid/2.5.STABLE3
Mime-Version: 1.0
Date: Tue, 16 Nov 2004 18:44:51 GMT
Content-Length: 0
X-Cache: MISS from squid1.mediageneral.net
Proxy-Connection: close

I can see in the access logs that http://my.domain.com/page2.html is
cached because it brings up a TCP_HIT:NONE in the access log. If I
try to purge everything containing the word page2 or the word domain
in the URL I get the following in my logs NONE:NONE
# squidclient -m PURGE page2
HTTP/1.0 400 Bad Request
Server: squid/2.5.STABLE3

X-Squid-Error: ERR_INVALID_URL 0

Below is my squid.conf file. I would appreciate any help.

Thanks again,
Nick
