ASP.NET URL Rewriting

How do I rewrite a URL in ASP.NET?

I would like users to be able to go to

http://www.website.com/users/smith

instead of

http://www.website.com/?user=smith

Try the Managed Fusion Url Rewriter and Reverse Proxy:

http://urlrewriter.codeplex.com

The rule for rewriting this would be:

# clean up old rules and forward to new URL
RewriteRule ^/?user=(.*)  /users/$1 [NC,R=301]

# rewrite the rule internally
RewriteRule ^/users/(.*)  /?user=$1 [NC,L]

Microsoft now ships an official URL Rewriting Module for IIS: http://www.iis.net/download/urlrewrite

It supports most types of rewriting including setting server variables and wildcards.

It also will exist on all Azure web instances out of the box.
