Is there a way to access referrer information from the server log in a ASP.NET web application?
I would like to know if a customer comes to my web app from a specific site and change the app’s behavior accordingly. I could have the webmaster of the other site include a query string, but to my knowledge this wouldn’t work because as soon as Tom, Dick or Harry posted the link somewhere else, the query string would be unreliable.
Is there a sure fire way for a web app to know where the user came from?
Why would you not just access the Request host header for the HTTP_REFERER instead of the log file? See here, but note that you are never guaranteed to recieve this information, nor is it reliable if you do.
