When I try to read the HTTP_REFERER server variable when the link is on a https page I get an an empty string. This question has been answered here before, but my experience is not consistent with the previous answer. Obviously some people are able to read the referer even when using ssl. Could be due to different configuration?
My environment is IIS6 on a Win 2003 server. I use a asp.net 2.0 web application for testing. It works perfectly when using http. (Request.ServerVariables["HTTP_REFERER"])
Appreciate any suggestions or comments.
