Troy thank you for taking the time. I am working without a browser, but just at the communications level (i.e. no user interface at all). On the other hand, I'm not trying to get a file from a user's machine. This is the scenario: I'm running an e-commerce site server. In this sense, I have my own server-side processes. One of my services is a report file generator, so when one of my users have been logged and requested this report, my server-side program creates this report and presents it in a PDF format. However, there is a special client which needs that my site (back-end process) could upload this report to his server. Unfortunately, he doesn't know anything about FTP. In his site, once you have logged in, there is a form which presents this to type or through the browse button specify the file to be uploaded. Okay, with this in mind, what I want to do is just automate this process, to eleiminate the need of loggin with username/password and go step by step just to upload the file. Up to this point, my program loggs in and passes every page perfectly (again, without a browser) but in this specific page it fails. I do not know how to send the content of the file through the HTTP request. If you know some literature about multipart/form-data submissions I will appreciate teh reference. I develop all my server-side programs in C++, and just the client-side is JavaScript, DHTML & HTML. Thank you again.
