would this work? (.dll question)

OK,

I wanting to work on this socket server, but want it to run on a web server with my .net application.

If i was to build a .dll that defined, started a tcplistener, and handled messages and so forth and then added it to a .net web application. And in my global.asax file under the application_start method, i was to define a instance of the .dll class and started it. Would that work? Meaning would that start up the .dll to act as a socket server so that I can... lets say take a flash client and have it connect to it?

Thanks,
Cedricany ideas if this would work or not?

Please advise,

Thanks,
Cedric
Someone has to know something about .dll's and .net and if this would work. I can't really find any info online about this, so this is my really only hope of source for this issue.

Thanks for any info you can provide,
