Redirecting a page with variables

[Masca]

Hi!  I have searched and searched, and I cannot find a solution to what I think should be a very simple redirect.  I need to permanently redirect:

 

www.domain.com/this_page.php?this=that

to:

www.domain.com/another_page.php?this=that

 

However, all my attempts result in a 404.  I feel so stupid :-(  Please help! TIA!

This is my current effort ('that' in my original post should always be 4 digits, e.g.: 1234):

 

RewriteRule ^this_page.php\?this=([0-9]+)$ another_page.php?this=$1 [R=301,L]

 

Where am I going wrong please!?

Anything after the question mark is considered to be the 'Query String' and this is ignored by RewriteRule. Does everything that references this_page.php want to go to another_page.php? If so then something like...

 

RewriteRule ^this_page\.php$ /another_page.php [R=301,QSA]

 

...otherwise if the redirect does only want to happen given certain values for the query string you will need to use a RewriteCond which can be done something like this...

 

RewriteCond %{QUERY_STRING} this=([0-9])
RewriteRule ^this_page\.php$ /another_page.php [R=301,QSA]

cags, thank you SO much!  I can't tell you how long that's been causing me problems!  It's now working perfectly.  Thanks again!
