Where's a good explanation of how URLs are parsed. Specifically: http://msdn.microsoft.com vs http://microsoft.com/msdn and why http://www.msdn.microsoft.com doens't work Program Manager MSDN Online (Windows Vista, Avalon, Windows Workflow and Visual C++) MICROSOFT Windows Vista Developer Center My Microsoft Blog

msdn.microsoft.com references what is known as a subdomain. A subdomain is a domain that is part of a larger domain. For example, microsoft.com has multiple subdomains, such as office.microsoft.com and msdn.microsoft.com. Each points to a specific Microsoft product area. microsoft.com/msdn is the address of the subdirectory where all of the information relating to MSDN is stored in the microsoft.com domain. Basically, a subdomain can be the assigned alias of a subdirectory, such that http://msdn.microsoft.com refers to the same Internet space as http://microsoft.com/msdn. www.msdn.microsoft.com does not work because subdomains are shortcuts to a specific part of the world wide web space of a domain. In other words, msdn.microsft.com is a sub-part of www.microsoft.com and is an alias for www.microsoft.com/msdn. So when you access the msdn subdomain, you are through address translation already supplying www. Here are some references: How Does DNS Work?[^] Also, RFC 1034[^] and RFC 1035[^]

http://www.msdn.microsoft.com/[^] also redirects to http://msdn.microsoft.com/[^] :) :) Vasudevan Deepak Kumar Personal Web: http://www.lavanyadeepak.tk/ I Blog At: http://deepak.blogdrive.com/ http://deepakvasudevan.blogspot.com/

Yes, in the zone file you can have almost anything redirect to almost anything. The folks at MS realized that some people type in the www even for subdomains, so they likely added a redirect to catch it.
