Hello, Marcel.
We'd like to figure out whether it's a Cassini problem or application's configuration/logic issue. Would it be possible for you to install HTTP tracer called
Fiddler on the box where your client (browser) resides. To see the trace in Fiddler, use real machine name or IP address (not localhost or 127.0.0.1) in the request URL. The trace might give you an idea regarding why this problem is occurring. Or you could export and send the trace to us for analysis.
Best regards,
UltiDev Team.
