Here is what I've got: RewriteRule ^(tags)/(.*)$ /tags.php?search_in_description=1&tags=$2&sort=2a&page=1 [QSA,L] PHP: which rewrites to: http://www.domain.com/tags/Tag+Name PHP: http://www.domain.com/tags/Tag Name PHP: or any other character you type in.. I'd like to force the links to go to the conically correct (the one with the + in it) URL. How should I construct the rewrite so it does this most effectively? If it can be done so that the first letter after the + is also forced into capitalization that'd be great, too.
