What I have:

redhat linux 7.3
apache 1.3.27
virtual host config with

DocumentRoot /www/htdocs/html
ScriptAlias /cgi-bin "/www/htdocs/cgi-bin"
DirectoryIndex index.cgi index.html

What I want to do:

if I hit http://domain.com/, the server returns index.html
If I hit http://domain.com/cgi-bin/index.cgi, I get the output from
index.cgi
However, If I hit http://domain.com/cgi-bin/ , I get a 403 forbidden
error.

Can you combine the ScriptAlias and DirectoryIndex commands?  I can
workaround with a sybmolic link if I have to, but I prefer not to.

To answer the question, either provide me with the info on how to do
this, or prove (probably via url references) that I cannot.
