WMS Layer with User/Password not showing

LukasKalt

Hi

I wanna add a WMS Layer which has user/password Authentification. When the flag skipCapabilities is false I get this error message:

TypeError: Error #1080: Illegal value for namespace.

When skipCapabilities is true, the map is blank. But I can see with Fiddler (tool where you can capture requests sent from your PC), that requests are sent to the WMS server. When I manually try these requests with the browser, I get an image of the map. Why isn't it shown in the Flex Application?

Thanks for your help

If someone has the same problem, i found a workaround.

The problem was, that with the authentification enabled, the flex API sends the request with POST. It seems that the WMS service can't handle that. So i implemented an HTTP Handler in .NET. In there i send the request with GET and not with POST. Set the proxyUrl property that it calls the HTTP handler and then it works.
