Re: How to select the directory index file for load balancing?

I'm just fishin' here... But I think it has to do with the way 
mod_backhand handles apache internal subrequests.

mod_backhand will only try to load balance things that are initial 
requests.  Here, the initial request is / and then it is expanded with 
DirectoryIndex to /index.php which is issues into apache as an internal 
sub request, which mod_backhand will not attempt to load balance.

This behaviour was selected to allow mod_backhand to peacefully coexist 
with modules like mod_gzip.

One way is to work around this is to use mod_rewrite.  I think you can 
rewrite all / to index.php with a 302 and that will work like a charm.  
If that isn't a desirable approach, then someone more clever than me 
can try to change mod_backhand to handle subrequests too...
