>>Hi,
>>>
>>>If I may ask you a follow up question, please. How to do you "translate" the IP in the URL to a descriptive name? For example, I was installing the app on another customer's server and they put the URL for the main page to be:
>>>
>>>http://somename.companyname.org/mypage.aspx
>>>
>>>Do I understand correctly that the "somename.companyname.org" is equal to some IP like "192.168.0.121"?

>>Yes. A browser (or whatever) has to be able to map the domain name ("somename.companyname.org") to a specific IP address and this is usually performed by DNS (Domain Name Servers). For the Internet http://www.internic.net/whois.html will show you the name servers for a specified domain name. Pinging a domain name will show the IP address in the results.

>I am sure you know what you are talking about. But when I installed the application on the customer server, he, right there and then set the URL for the application. He didn't know the directory name I would be creating so he could not have registered it before hand. But he set the URL to be "somename.companyname.org". How do you think he did it?

Was this an in-house server on their own domain? If so then they could be using there own DNS or Active Directory. Or even something as crude as mapping the URL in the HOSTS file on the client machine. In the end the principle is the same - anything accessing the site via its domain name MUST have a method of obtaining the IP address.
