Why are you doing that in a jsp? You can do it in an action, but it
will not work that well (but it will work better tahn in a jsp, i
promise).
The other issue is that a URL ending in /foo.do?name=value will not be
seen by IE as a pdf. You should probably use a servlet for this
instead, then you can map the URL like the one above as this:
/foo/name/value/file.pdf, that will trick the browser into thinking
that it is just a static file.
Another problem you will have is that if you are using ssl, IE will
not allow acrobat to read from the cache. Your users will have to hack
the registry to make it work.
