Forums Scripts & Popups Authorized Downloads

Hello, I have an updater I wrote for mIRC. It checks a text file on my site and downloads files in the folder.

I also have a forum and I notice there are .htaccess files. Im thinking these files make it so you have to be logged in to access the files in the folder.

I want to do the same with my update files. I want to make it so you may only access them if you use my update script through mIRC.

Any ideas on this?

This is really an Apache (or whatever HTTPd service you're running) question.

If it were apache, you could do checks on the user-agent and restrict access that way (as your updater will always have a fixed string you can control).
