http_referer does not work in IE?

I was creating a banner in Flash but when I was testing it out in various browsers I discovered that Internet Explorer doesn’t carry over the “http_referer” variable to the target website.

Example:

Site A has the flash banner. When you click on it, it takes you to Site B. When I look at the logs for Site B, I see a referer next to each hit for every browser - except for IE. IE doesn’t carry over the referer.

This is crazy. Is there anyway I can fix this? It’s sort of possible to trick it by using the _url variable… but that won’t tell me the name of the HTML file the flash is embedded.

Any ideas…?

Thanks

Anyone?
