.htm vs. .html and external linksS

sometimes when an external site links to ours, they use a link ending in .htm

In our FURLs, I have the suffix set as .html

Can I set up a redirect or something so that a link ending in .htm will be just as valid as a link ending in .html?

This plugin will handle that:

The following should redirect if you want www.sitename.com/page.html:

www.sitename.com/page
www.sitename.com/page.htm
www.sitename.com/index.php?id=56 (if this the ID for this document)
etc.

Hmm... in my undestanding, SEO Strict URLs plugin does not redirect ’page.htm’ to ’page.html’...

I think you’re right and it would result in a 404.

Huh, I could have swore it would have worked for that case...guess not.

tkfm is right, I just looked at the snippet.

I really would like to have this capability, if any one else has other ideas, I would be eternally grateful.
