Re: [squid-users] RE: squid will not refer index.html

Seems to have worked fine. Only oddity is that the request for index.html was
considered a fresh both in the browsers cache and in the Squid cache in the
Tomcat 4 case.

But it is a bit odd you get HTTP/1.1 replies. You should not..

I would suggest clearing your browser and Squid caches. Perhaps there is an
old copy of index.html cached that Tomcat thinks is more current than the
current Tomcat 4 version.. (such things can happen if a new file has a date
that indicates the file is older than the old copy...)
