Re: [squid-users] SQUID and ASP - Part II

This server seems to be very picky about the User-agent used. Does not
actually seem to be a Squid problem at all.

If a request with the Konqueror User-Agent string logged below is sent
then the ASP code on that server crashes.

If a blank User-Agent, or one of Netscape is sent then it seems to work.

Also confirmed by trying some browsers:

If I use Konqueror going direct to the site then it fails.

Will probably start working for Konqueror users if you use the
anonymization feature of Squid to remove the User-Agent header, but then
many other sites will fail in similar manners..
