I'm having trouble with a 301 redirect on dynamic urls. I am trying to redirect urls like so:

http://www.domain.co.uk/pages.php?id=1&c=giglist

to new url:

http://www.domain.co.uk/gigs.php

+

http://www.domain.co.uk/pages.php?id=3&c=contact

to new url:

http://www.domain.co.uk/contact.php

etc....

This doesn't seem to work.

Redirect 301 /pages.php?id=1&c=giglist http://www.domain.co.uk/gigs.php
Redirect 301 /pages.php?id=3&c=contact http://www.domain.co.uk/contact.php

any ideas?
