.htaccess url rewriting

Question

can anybody please tell me the rewrite rule so I can make a URL like this:

From:

http://www.mysite.com/info/?file=someinfo.nfo

Into:

http://www.mysite.com/info/someinfo.png

Thanks in advance.

Answer 1

RewriteCond %{QUERY_STRING}  ^file=([^.]*)\.nfo$
RewriteRule info/ info/%1.png

(will fail if the filename contains a "." other than the one before the extension)
