Hi,
You're trying to cache a pdf file/attachment? why? What's the purpose
of trying to do it that way? Why don't you just send it to the client
when they ask for it?
Also, there's no way on the server to 'force' content to be cached on
the client. The browser has to specifically allow it. All I can think
of is the browser needs to set if_modified_since headers in the
request for the server to respond with a 304, but I've never tried to
cache a pdf file or attachment.
