httpd - Multiple index files?

[Romain]

Hi there, 
 
Is it possible to supply multiple index files to the directory index directive? 
I mean, I would like to write something like that in httpd.conf: 
 
       directory index "index.html" "index.php" 
 
which would mean that, if the directory contains "index.html", then the server 
should serve it first, if not, then try "index.php", otherwise the standard 
error. 
 
So far, I could only make accept one file to the directory index directive. 
 
 
Or should I do it in another way? 
 
Thanks. 
 
Best, 
Romain
