Re: Hostname/port from ServletContext

[Tim Funk]

You can't. That is because the context runs in some type of service 
which will present you with the requests. So only at request time can 
you know the hostname and port number of the server.

For example:
I have a web server which listens on ports 8080-8090 inclusive. That 
means that anyone could hit my web pages via:

http://www.ineedmorecowbell.net:8080/myPage.jsp
http://www.ineedmorecowbell.net:8081/myPage.jsp
http://www.ineedmorecowbell.net:8082/myPage.jsp
And I could complicate things furthur by adding another ip address to my 
server so I could also say:

http://igotthefeverandtheprescriptionismorecowbell.net:8080/myPage.jsp
http://igotthefeverandtheprescriptionismorecowbell.net:8081/myPage.jsp
http://igotthefeverandtheprescriptionismorecowbell.net:8082/myPage.jsp
In this scenario, myPage.jsp could be hit by many different ip addresses 
and different ports.
