HTTP_REFERER blank

[SStory]

Need to know what page called my aspx (page via a form)

calling page could be aspx or asp.

sometimes
HTTP_REFERER is blank....

Why?

Is there another variable to use to get it?
Ideas?

Thanks,

Shane

HTTP_REFERER will be blank for a number of reasons (e.g. if the user sends
the request directly, if the user sends the request from a different IE
security zone, if user has a privacy proxy installed, if the user sends the
request from a page that was transferred using SSL, etc).

What are you using this variable for? You could just make your posting form
contain a hidden input field containing info about the post form.

You should never use this field for security decisions, as it's easy to
spoof.
