Important : Referer Problem

[berkdulger]

Our aim is understand the referer.

When we enter the url in a direct way

request.getheader returns null .

However, if we use a link to go the url we can take the referer.

We tried normal ways

Can you say the problem is on Jsp or on Browsers or on approach?
Can you help Us? What is your advice?

Thanks a lot.
