mod_rewrite and SEO friendly url

I've got the following rewrite to work in .htaccess:

RewriteEngine on
RewriteBase /tmp/
RewriteRule ^([^/]*)$ /cgi-bin/app/file.jsp?v1=$1 [L]

However, I entered the same into httpd.conf, couldn't get it to work:


Options Indexes FollowSymlinks
AllowOverride None
Order allow,deny
Allow from all
RewriteEngine on
RewriteBase /tmp/
RewriteRule ^([^/]*)$ /cgi-bin/app/file.jsp?v1=$1 [L]


Can anyone see my mistake(s) and recommend what to do to fix this? I
have used it on both Apache 2.0.52 and 2.2.4, without any success on
httpd.conf.

regards,
Rudy
