php - Rewrite an url with htaccess -

i rewrite url

http://mydomain/index.php?s=profil

to

http://localhost/profil

i have seek in .htaccess:

rewriterule ^([^/]*)$ /index.php?s=$1 [l]

but not work (error 500).

i guess wanted url http://urdomain.com/profile show content http://urdomain.com/index.php?s=profil, illustration of how this:

rewriteengine on rewritebase / rewriterule ^content/([a-za-z0-9-]+)/?$ index.php?s=$1 [nc,l]

this rule redirect page urdomain.com/content/alphanumeric123 index.php?s = $1

explaination:

[a-z] - lower case characters [a-z] - upper case characters [0-9] - numbers
