w3c-validation

问题 I am using MVC4 project and doing URL rewrite on Server side in RouteConfig and appending .html at the end of url of every page.. www.mysite.com/home.html I have couple of pages and those pages are linked with home page (every think is working find in browser). But when I validate using W3C link checker, I get broken link error message. I really don't know what can be issue.

It's actually very useful including autocapitalize in the 'email' and 'website' fields in forms, as there's nothing so annoying as having to unselect the SHIFT key when filling in either of those two inputs.
