PDF download is being corrupt if downloading using a non proxy server

[boros kabos]

Dears,

Have an online .Net 2.0 aspx + Ajax which downloads PDFfiles based on below code, the code is working with no problem under ISA server (The server is hosted behind an ISA server) and any connection which has a proxy server.

When trying to download the file using a non-proxy connection (Real static IP connection) the PDF file is being downloaded but it is corrupted. Checking the PDF file under notepad i can see that the code of the page is being added to the PDF file.

Help am clueless.
