Htaccess throws 500 internal error with rewrite condition for non existing directory?

Your rewrite rules are looping. The regular expression (^/+)/?(.*)$ is matching the rewritten URI sites/something/something and it's looping indefinitely (so your URI starts looking like: sites/sites/sites/sites/sites/sites/sites/sites/sites/something/something etc).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
