htaccess rewrite rule, old URL to new - .htaccess

Question

A bit of help fellow SO people.
What I have at the moment (based on some code I used for a different type of URL).
I want the first URL to redirect to the second, with no query string included afterwards
This is what I have to so far.
RewriteRule ^(page.php?id=missionstatement+)/?$ http://example.com/why/mission-statement [R=301,L]
RewriteRule ^(page.php?id=ofsted+)/?$ http://example.com/how/ofsted-report [R=301,L]
RewriteRule ^(page.php?id=governingbody+)/?$ http://example.com/governors [R=301,L]

Answer 1

Here is the rule (will redirect 1 URL):
RewriteCond %{QUERY_STRING} ^id=whatever
RewriteRule ^page\.php$ http://%{HTTP_HOST}/how/somehow? [R=301,L]
This rule intended to be placed in .htaccess in website root folder. If placed elsewhere some small tweaking may be required.
I have used %{HTTP_HOST} -- this will redirect to the same domain as requested URL. If domain name has to be different, replace it by exact domain name.
The ? at the end of new URL will get rid of existing query string.

Ahoy!
Give this a whirl:
#check mod_rewrite is enabled
<IfModule mod_rewrite.c>
#enable mod rewrite
RewriteEngine On
#set working directory
RewriteBase /
#force trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ $1/ [R=301,L]
#bootstrap index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^page.php\?id=(.*)$ http://www.willans.com/page.php/$1 [R=310,L]
#end mod rewrite check
</IfModule>
It's been a while since i've done any web dev, but that should be a push in the right direction at least ;)
