I'm testing MSMQ 3.0 via HTTP. Our network configuration is as
follows:
A. Windows 2003 Server Edition in Site1
    Queue messages are sent from here.
 
B. Windows 2003 Web Edition in Site2
    This server has a public IP;
    In this PC is installed an ISAPI filter called ISAPIRewriter that
forwards all HTTP messages to C.
 
C. Windows 2003 Server edition in Site2
    This PC is configured with a public queue and HTTP queue support.
 
My tests have outlined three situations:
 
1. A sends a generic HTTP request to C (through B)
    In this case, B receives the message, forwards it to C which
replies with a "200 OK" and the response arrives correctly to A
 
2. A sends an MSMQ 3.0 HTTP request to C (through B)
    In this case, B receives the message and replies with "400 Bad
request" without forwarding the request to C
 
3. B sends an MSMQ 3.0 HTTP request to C
    In this case the message arrives to C wich replies with "200 OK"
 
Now, my question is why in case 2 I get the "400 Bad request" error?
Could it depend on the fact that the message is discarded by IIS on B?
Is there a way to forward MSMQ messages from B to C without installing
a public queue on B (I can't install a public queue on B anyway,
bacause it's a Windows 2003 Web Edition machine)?
 
Thanks in advance for your support.
