I have a website in PHP and website in .NET. Both are hosted on the same server under Windows 2008 R2. In the header of the PHP site there is a link to the website in .NET, but the link is not working. When the user clicks the link in the PHP website, the sever variable HTTP_REFERER is created but the value is being set to blank. The same works correctly on a Windows 2003 server with IIS 6 and there was a value in the HTTP_REFERER variable.
I appreciate your help
