[thelist] redirect .htm

[Bob Meetin]

.htaccess:

Options +FollowSymLinks
RewriteEngine On

RewriteRule sowhat.htm index.php?option=com_content&view=article&id=120&Itemid=125
RewriteRule sowhat.html index.php?option=com_content&view=article&id=120&Itemid=125

And the question, neither sowhat.html or sowhat.htm exist, but for the example, when I do the .html redirect it works fine.  With .htm extension it fails and I get a non-existent page browser message. Of course the original files are all .htm.

Is there an apache server config that perhaps controls this?
