Topic: PDF viewing problems with IE with 'no-cache'header
Conf: (P-PDF) Developers, Msg: 55559

We are attempting to serve up 'sensitive' PDFs (like the
Web site) with HTTP headers set for "no-cache" - ie.
"Cache-Control : no-cache" and "Pragma : no-cache". (This is
like the http-equiv one might use in a head 'meta' tag... only it's
the real thing, not an 'equiv')
We are also setting the "expire" date to the past.
(All are efforts to prevent the "caching" of the files - they
should only remain if the user downloads to disk.)
Unfortunately, the Acrobat plug-in appears unwilling to
display these PDFs with 'no-cache' headers or 'expired'
Can anyone offer any insights or work-arounds?
Much thanks in advance!
