Server is IIS5. Need a control that opens a port...

[Jim Carlock]

I'm wondering how it might be possible to either:
1) Open a port on an IIS server and watch what's coming
over the port.
or
2) Open port 80 and watch for certain information coming
through and if it's not a specific message, pass control to the
IIS server to process the message as normal.

The end result is that there are messages being sent to the
server. The messages will likely be sent over port 80 (http).

They will be coming from end-user software to notify the
server of different things and pass back serialization numbers.

Need some advice on how to accomplish this.

Hi Jim,

ISAPI is what you're looking for Jim. It allows you to program HTTP filters
at the server.

I understand the concept of ISAPI, of putting a DLL file in there. Is
there a way to programmatically do this from a website? If it's
possible to do it and apply it to only my website on a host that hosts
about thirty other sites, would you be able to provide a link to some
site that might get me started?

It almost sounds like I'm going to run into the same problems I'm
already having with not being able to register a DLL file on the server.

I'm ignorant on how to effectively use the registry to register libraries
and executables. If you or anyone else knows of some links to sites
to read things, I'm looking to do a lot of reading.

Jim,

If this is on a shared server with an ISP / WPP they may not allow you to
install an ISAPI filter. I'd check with them first. There is an excellent
book on writing ISAPI "Using ISAPI" by Stephen Genusa It's dated but the
technology has not changed that much.
