I've never had a problem using this before, but we just got a call from a customer on winxp/ie6 and this is not working for him. I assign the value of request.servervariables("HTTP_REFERER") to a variable and response.write the variable to the page. On any other computer, it works fine, but on his, it is blank. Anyone know if there is a bug with servervariables or if it's just unreliable? Thanks.
