I have a c-compiled CGI application that I need to execute from the DocumentRoot of my Apache server. The CGI file is called index.cgi and is located at /usr/lib/cgi-bin/index.cgi.

I have the following Directory definition

<Directory "/usr/lib/cgi-bin/">
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    AllowOverride None
    Order allow,deny
    Allow from all
    DirectoryIndex index.cgi 
</Directory>

I have the following VirtualHost setting:

<VirtualHost *:80>  
    ServerAdmin webmaster@localhost
    DocumentRoot /usr/lib/cgi-bin
#   ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

    ErrorLog /var/log/apache2/error.log     
    LogLevel warn   
    CustomLog /var/log/apache2/access.log combined

</VirtualHost>

If I go to 127.0.0.1 or 127.0.0.1/index.cgi I get prompted to download the index.cgi file, however if I enable the ScriptAlias in the vhost configuration block and go to 127.0.0.1/cgi-bin/index.cgi I see the output of my CGI application.

I had originally solved this problem with mod_rewrite, however that worked on my test system the target (embedded) doesn't have that module available so I'm looking at another route (again).
