can webserver recognize webbrowser control vs internet explorer software when user load page ?

why there is diffrent behevior and how i can manage that ?

thanking in advance.

That sounds like maybe it is reacting to a different cookie value or similar. WebBrowser is IE (to most purposes). A 500 is at the server, but WebBrowser is the client.

You might be able to hook WebBrowser to supply a different user-agent, but by default it should appear the same.
