CGI question

I would like users to be able to download files from my web site, without showing them the URL of the file.  I can hide the URL in the HTML code, but the browser the user has will display the file's URL. With HTML files I provide my customers, I call an .asp script to write the file to the browser, thus hiding the html file name, but I haven't figured out how to do this when downloading files. I've looked at .asp methods as well as perl. Maybe there is some way to write the binary stream out to the browser! Thanks in advance if you can help.

I would approach this by writing a script (in perl) that opens the file to download and outputs it to stdout, effectively this will output it to the browser.

The main issue will be that the browser will be expecting a particular mime type. Some types the browser will deal with itself, such as text or gif images. For those types that the browser does not know about it will prompt if the user wants to save the file. For example exe files are handled this way.

If it was an exe file that was being downloaded then you would output the following prior to outputting the exe file.

print "Content-type: application/octet-stream\n\n";

This would result in the user being prompted where to save the file to. Unfortunately you will also find that the default file name will be the name of the script, there is no way to change this default.
