? I don't get the problem. If you create a PDF
a) with an external application (e.g. latex, pdfcreator, etc.) you could
ether do the trick with the x-sendfile (let your webserver do the job)
b) create the pdf-file in memory (e.g. with a c++ library), then you can
stream the pdf straight out with `response().out() << f.rdbuf();`

You don't have to read it in memory, so there should be no problem
