Our application is for a very limited number of end users, and we can pretty much tell them to use IE 4.72 and higher. So I hope I'm ok on this one. I really don't feel like trying to implememnt Microsoft's Active-X solution. Ha, wait till you install 5.0, everything's different there again. Then 5.5 changes everything again.

RE: servlet called thrice on IE 4.0
I can't specify the source of this advice exactly, because I forgot it (it was somewhere on Microsoft's website), but what the article said was that when IE sends these multple requests, they are actually different in something like UserAgent http header (a better header they couldn't find!). Only the last request needs to return the actual PDF document, the first one or two requests only look for Content-Type of the response. If you investigate (by dumping all fields from the HttpServletRequest) and find something of this kind, please post to the list.
