I have apache set up to serve for a local intranet.

I have an "index.html" in the root folder.
If I type "http://myintranet/" into browser, the index.html page comes
up (note that "index.html" was NOT included in address)

I have apache set up to correctly serve .php pages (php as a module).
If I enter an explicit address ending ".php" the page is served fine.

Is there any way to set apache so that "http://myintranet/" would cause
apache to serve "index.php"?

I've tried setting "DefaultType application/x-httpd-php".
