If I understood well, all you need to do sending a Content-Type header with the appropriate value (e.g. application/pdf for a PDF document) and then you can pump your data through the connection, it does not matter if yuo're copying an existing file or if you're generating it on the fly.

Among the many sources of Content-Type values:

• your Web server configuration;
• this link.

If you know in advance how many bytes you're sending, a Content-Length header is a good thing to output as well.

You can set the Content-Type header in many ways, using the CGI module you can use for example the header method.

Happy sending!
