>I have several Web sites which need to be handled from the same Web site. So, basically, I have a setup which indicates a redirection to a URL. This works. Basically, whenever there is a hit into those Web sites, the browser redirects to the same page on the main Web site. However, I would like to pass a parameter so I would know that the page being processed came from a specific domain. Is that possible?

I have resolved that issue. See thread #1437758 for more details.
