title: ASP.net MVC performance with extensionless url on IIS 6
body: <p>We are getting ready to do a an initial deployment of an ASP.net MVC app on IIS 6 running on Windows Server 2003. We've been reading about performance issues involving the use of extenionless urls in MVC applications specifically in the case of removing the '.aspx' extension from the controller portion of the url.</p>
  
  <p>Has anyone who has deployed an MVC app in the past experienced any performance degradation in this area? Was it noticeable, and was it worth it for having the cleaner URLs? Our application will rarely have to deal with more than 1000 or so concurrent users.</p>
  
  <p>Edit: Thanks for all the responses, it's working quite well, although there are a few strange requests going through as some people mentioned, I think we can work around these using the suggestions mentioned here.</p>
