I'm no expert in mod_rewrite at all and I'm trying to add a condition to the rule below to:

1. match which is not equal to 'share'
2. not match anything with a dot in it

RewriteRule ^([^/]*)$ http://domain.com/directory/index.php?key=$1 [L]

http://domain.com/directory/share will not be matched (share)

http://domain.com/directory/foo.php will not be matched (contains a dot)

http://domain.com/directory/abcde will be matched

http://domain.com/directory/abcde-4 will be matched

All ULRs will not have a trailing slash

Any help will be much appreciated
