Re: [squid-users] 302 response

Hi

Squid converts hostnames in URLs to lower case. See line 259-260 of
src/url.c.

RFC 2068 states that comparisons of hostnames MUST be case-insensitive.

I believe Java Webserver (at least the authentication servlet) does
case-sensitive comparison of hostnames in URLs and Host: headers. If the web
server's hostname consists of mixed cases e.g. redmesa.Microsoft.COM,
comparison will fail. The servlet will then create a redirection hoping to
get the correct hostname (with the correct case).

P.S. Do you work for Sun? 8)
