Hmm?
This sounds more like it is related to content negotiation,
which among other things is used to deliver documents in a
language the reader understands.
Does it mean that proxy servers don't know about content
negotiation?

If proxy servers don't know about content negotiation, then
I can just as well use SSI whereever it is of use, but as it
is now, I don't use it much.
Generally I use links without a file extension, so I don't
know how proxies making caching decisions based on file
extension will behave. Well...
Checking out the documentation, it is more likely that
"mod_expires"[1] is the solution, if you want proxies to
cache server side processed pages.
Play well,
Jacob
