.htaccess - How to add dot in htaccess rewrite rule regex? -

i want create url structure dir view (example.com/dir1/dir2/file) using htaccess mod rewrite as

rewriteengine on rewritebase / rewriterule ^/?([a-za-z0-9\-=&_@/]+)/?$ get.php?u=$1 [qsa,l] 

the code above works fine except if try add dot like

rewriteengine on rewritebase / rewriterule ^/?([a-za-z0-9\-=&_@/.]+)/?$ get.php?u=$1 [qsa,l] 

the .htaccess breaks. "internal server error"

the problem if add dot in pattern pattern matches target url get.php , rewrites get.php get.php on second rewrite cycle. results in infinite loop/rewrite loop error.

you need rewritecond prevent :

rewriteengine on rewritebase / rewritecond %{request_uri} !^/get.php rewriterule ^/?([a-za-z0-9\-=&_@/.]+)/?$ get.php?u=$1 [qsa,l]
