Error is .htaccess - Redirects not working and its very strange

My site has just recently launched a bunch of new product pages, replacing the old ones.

Here is an example of a redirect I want. One going from the old page...redirecting to the new page. I checked Google webmaster and said that there was a not found error for the second link.

Redirect 301 /it-infrastructure.html http://www.example.com/managed-enterprise-services.html

Redirect 301 /it-infrastructure http://www.example.com/managed-enterprise-services.html

So the .html one is redirecting fine...but the one without the .html extension is not. BUT...what's strange is that I have a bunch of redirects from the past that don't use the html ext and work fine, such as:

Redirect 301 /broadsoft-web-portal http://www.example.com/broadsoft-web-portal.html

and

Redirect 301 /business-voip http://www.example.c开发者_运维知识库om/business-voip.html

Anyone have any idea why this isn't working?

Add to your .htaccess this line

Options -MultiViews
