location for paypal ipn's notify_url

[Mandler]

I'm just learning about using PHP and Perl to interact with other processes.

PayPal has an Instant Payment Notification (IPN) feature that can post to my website and cause a script to verify the transaction with PayPal, send an email, insert a record into MySQL, etc.

Where is the most secure location for the notify_url? To date, I have located all my scripts in the cgi-bin with their permissions set to 0755. I assume (perhaps wrongfully) that I cannot give PayPal a pointer to that location(?). If I can, how do I specify the URL ("http://futurequest.net/[something]")?

If, instead, the location is a www sub-directory ("www.MyDomain.com/someplace"), do I simply have an HTML document that triggers my script and, if so, how do I pass the arguments?

I'm sure (make that "hope") this is much simpler than I'm making it.

Thanks... a.m.
