ok what Im doing normally works but since my rule "includes" itself is giving me issues and can't find a solution after hours working on different options.

I have a .htaccess with:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/3.15.0/(.*)
RewriteRule ^(.*)$ /3.15.0/$1 [L]

this is for my software versions, I have a program that can request sometimes versions that are updated and in the server may be behind a couple version so I want to be able to say that whatever is comming in forward to the latest version that in this example is 3.15.0

/var/www/nameblabla/3.15.0

my .htaccess is on /var/www/nameblabla/.htaccess

so the first Condition is to ignore request that already has the right path and version.. the second should be to grab all request and forward to 3.15.0... and of course not loose the path to the files I want from inside that should be the same. so far I can only get it to redirect to such directory but will loose the path and others I get the "Request exceeded the limit of 10 internal redirects" I guess this is because Im including the 3.15.0 path

Any help or another way to do this with out mod_rewrite?
