My server only recognizes index.html files as directory index's. I would like it also recognize index.htm and index.shtml files.

How do I configure the server to recognize index.htm files as indexes?

This would seem odd, but...

In srm.conf :

# DirectoryIndex: Name of the file or files to use as a pre-written HTML
# directory index. Separate multiple entries with spaces.

DirectoryIndex index.html index.htm index.shtml ...

Also if you are running a newer version of apache, they now combine the files, so if you dont have srm.conf, add it too httpd.com

Thanks, for the help. My server has both an srm.conf and an httpd.conf The srm.conf is an empty file and the httpd.conf is a long 43 KB file. A representative from tech support was able to get it to work by changing the line

<IfModule mod_dir.c>
DirectoryIndex index.html
</IfModule>

in httpd.conf to

<IfModule mod_dir.c>
DirectoryIndex index.htm index.html
</IfModule>
