Application vs. Web Servers

[Matt]

What is the difference between an application and web server? I currently
have a CGI web application on Windows NT that I manage through IIS. What
are the steps involved in moving the application to a separate (application)
server? The user would come in through the original NT Web Server, but the
CGI application would run on a different application server. Are there tools/additional
engines so that the Web server knows what application server to go to? Do
I need to do anything different in the code of the CGI application?

Thanks for your help in advance.

You may check this page:

It gives a quick overview of Web Server and App Server works together. But
to roughly simplify, an App Server can be seen as a big CGI, which manages
a collection of smaller processes.

Also take a look to the App Server Definition at:

I hope it helps.
