We have a web application running on server and it posts http requests via XDomainRequest (because of IE9). 

There are lots of client computers which have a console application listening on a port via socket listener. Clients open web application with their
IE9 browsers and when they click on a link, the web page sends requests like that:

"<https://localhost:portNumber/applicationName/doSomething>"
"<https://computerName:portNumber/applicationName/doSomething>" 
"<https://ipAddress:portNumber/applicationName/doSomething>"

The second and third requests are made to console applications of other users' computers.

The problem is that if requests come with localhost, console application does not have a problem about reading incoming data and sending response back. But 
if the request comes with computer name or ip address then browser shows certification warning and wants user to click on 
"Continue to this web site (not recommended)" link.

We thought creating three different certificates via code.
But even using sslstream with three of them is possible we cannot decide to select true certification because we make authenticatiton first and then receive data. So when we catch incoming request the authentication must already be done.

Another way is forcing socket listener or sslstream to behave all these three requests as if they are localhost. So for each one authentication will be made as localhost. But I could not find an actual way for that.

Here is the code. I give the code because maybe there is some wrong usage of SslStream.
