I am using IE 5.5 SP2. My request for a PDF document is being sent twice. Does anyone has a working servlet which serves PDF requests in one shot.

One you'll want to look out for User-Agent='contype' in the request header, and only return the content type, not the actual content. But this isn't enough (even though Microsoft says it is). IE < 5 likes to request the PDF doc, then kill the request, then request the contype, then request the doc again. Except sometimes, and under no reproduceable set of conditions I could discern, IE accepts the whole document on the first request. Which means you can't just only call FOP and return the whole doc on the third hit. The only full solution I've seen so far is to cache the PDF byte-array in the session after the first hit, then return it if requested on the third hit. (credit Jim Urban I believe) This doesn't save you from sending the PDF out over the wire twice, but it does save calling FOP twice. And so far the latter has proven to be much more time and resource-consuming. I've attached the servlet I use to generate HTML and PDF. It's kind of a mess, but you should be able to find all the pieces. One note: it's possible setting the 'Content-Disposition' as described below may clear up the problem. I remember experimenting with Content-Disposition a long time ago, but I didn't like the way it brought up two consecutive 'Save As...' dialogs.
