Ok, that would be cool if Tomcat can be configured that header compression and NPN should
not be used (or no SSL at all). SSL/TLS connections (without NPN) are supported natively by
.Net so that a NPN TLS tunnel wouldn't be needed then.

Ok, thank you for your efforts!

Yes, I agree. I could modify the SPDY redirector so that it appends x-headers for the client
IP etc. (but currently I don't know much about transferring certificates - is that what "CREDENTIAL"
frame in SPDY is for?) 

Thanks!
