Thanks, Anup. I did read the vcl man page several times. The technical
problem with Varnish is that, if I set it up to cache things even if
Cookies are present, my site malfunctions because pages for logged-in
users are cached. I have to make the caching conditional to the login
Cookie specifically (I did use a conditional "hack" to get this in
default.vcl) otherwise the site completely malfunctions.
The optimum behaviour would be Varnish caching static files
(img,css,jpg,png, based on response HTTP headers) and not caching
dynamic ones. But as it currently stands, Varnish configuration
language doesn't allow caching to be controlled based on the response
headers, only on the request ones. Squid, however, does.
