Double User-Agent Header in HTTP Request
I'm having problem with double User-Agent header in my Requset. Using httptrace I got this message "Parsing of request (request ID 0xF70000008000009B) failed due to reason: MismatchDuplicateHeader. Request may not be compliant with HTTP/1.1"
What is the easiest way of handling this on IIS. I would like to remove one of these two User-Agents, and continue with execution. Is it possible?
POST /WCF_myService/myService.svc HTTP/1.1\r\n
User-Agent: SonyEricssonZ530i/R6AC Java/SEMC-Java/2.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 UNTRUSTED/1.0\r\n
User-Agent: Profile/MIDP-1.0 Configuration/CLDC-1.0\r\n
Via: 1.1 proxy-miep-1.telenor.rs (squid/3.1.1)\r\n
Thanks in advance!

I don't know if there is anything you can do on the server side. You should probably identify where in the client the extra header is being injected and fix it there.
