Subject: Re: Specifying a Proxied URL on the CERN Server

Ari,

Thanks very much for the info. Our guys will be trying to make it work shortly.

Phil Hallam-Baker suggested doing an MD5 of the pathname to solve the cache
name problem.

Our queries are likely to be short, but there are many terms and possible
combinations
in the worst case.

Why not just apply the quotation stuff for URLs to the file names?

The backend is a lisp machine running the CL-HTTP server.

I added 1.0 conditional gets based on if-moified-since and Expires headers
on relevant outgoing requests (get, head, post).

Will the cern server exploit this information effectively to minimize cache
refreshes?

Is the CERN server going to do something reasonable with form submissions?

When I get a few hours, I'll finish upgrading CL-HTTP to full proxy caching
and let you know
if I come up with something any better for cache names.

We've got a fairly major collaborative WWW+email system rolling out.
