How to restrict user to enter direct url

Advay Pandya asked:

Hi all

I want to restrict user to enter direct url.

If user tries to enter url then it should redirect back to the last page that the user visited.

I used Request.ServerVariables["HTTP_REFERER"] . When user enters direct url then it returns "Null".

So I can get , user entered direct url

But how to redirect the user to the last page he/she visited ?

Is there any preferable alternative way to implement this ?

Please advise.

Thanks

Advay Pandya
