Clear HTTP_REFERER

[notrut]

Hi,

Is it possible to clear out the HTTP_REFERER??

I've tried setting it to nothing, but it does not work.

(i.e. set Request.ServerVariables("HTTP_REFERER") = nothing)

I want to prevent people from hitting the back button and then submitting a form they have entered in twice.

Any help would be greatly appreciated!!

That link describes the Server variable you are asking about. It says to clear it you need to redirect the user. Basically have your form input page, then submit page, finally redirect to the results page. According to this it would clear that variable.

I didn't test it so let me know if it works.
