With WordPress, they change my quote with something weird. Try changing the quotes to a normal text quote and upload again.

I don’t know about ASP, Andrew, but that’s how I do it in PHP. You see, we use this, as in example, in download.php. But we don’t want to call download.php directly. We only want it to be called using include() (or #include in ASP) by ipn-handler.php.

When being called using include, $_SERVER['SCRIPT_NAME'] returns the name of parent script, which is ipn-handler.php. When being called directly, of course it will return its own name, like download.php…

Thanks Kidino for your reply but your code won’t work because Request.ServerVariables(”script_name”) referes to the current script and not to the script that redirected us to the current page. I was told that Request.ServerVariables(”http_referer”) might do the trick but it refers to the domain that redirected to the current page and not to the script. What about the usage of a session variable to protect the download page? Any thoughts on that? Thanks

Try this …

if Request.ServerVariables(”script_name”) “ipn-handler.asp” then
… do your stuff …

end if

I haven’t code ASP for ages…

I’m a asp.net developer. What is the asp.net equivalent of the php code:

if ($_SERVER['SCRIPT_NAME'] != ‘/ipn-handler.php’)
