 12  * Handles HTTP digest authentication
 13  *
 14  * 
HTTP digest authentication can be used with the URI router.
 15  * HTTP digest is much more recommended over the use of HTTP Basic auth which doesn't provide any encryption.
 16  * If you are running PHP on Apache in CGI/FastCGI mode, you would need to
 17  * add the following line to your .htaccess for digest auth to work correctly.
 18  * RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
 19  *
 20  * 
This class is tested under Apache 2.2 and Cherokee web server. It should work in both mod_php and cgi mode.
