RE: [squid-users] Illegal character in hostname!

Hi,

I have had the exact same problem. BUT, I think I have encountered ANOTHER
problem while trying to prevent access to the cache from clients who use
this buggy software called "babylon".

Since the clients have generated a huge ammount of logging, I wanted to
prevent access to the cache from these clients. So I created the following
ruleset:

        acl client_with_babylon src 192.168.1.1/255.255.255.255
        http_access deny client_with_babylon

This ruleset had no effect whatsoever (at least not for the Babylon
software).

It seems as if squid cannot handle this due to the URL parsing. I think that
squid does the URL parsing before it looks at the acl's??

So, when an invalid request arrives, squid analyzes the URL, and loggs an
error prior to reaching the acl list. Is this correct? If so, I think you
may want to change this behaviour in upcoming versions of squid.
