headers / content-type

[noon]

I am going to make a file available for download (a Firefox extension) but I want a simple way of recording how many times this particular file has been hit.  So, using the following code I can keep track:

increment_hits();

header("Content-Type: application/x-xpinstall");	
readfile('extensiondev.xpi');

 

Now, this is probably an apache question, but I figure you guys would know.  I want this to be transparent to the users.  How can I make this php file actually take on the extension .xpi and have my apache server handle it, using strictly an .htaccess file?

I can't seem to edit it again. This is solved using mod_rewrite
