301 permanent redirect with parameters

I have a lot of duplicated pages with parameters because an anarchic short´s url methodology:

real urls:
http://mydomain/forum?action=viewthread&id=5665
http://mydomain/forum?action=viewthread&id=5665&post=12

old url´s:
http://mydomain/forum-id5665.html
http://mydomain/forum-id5665-post12.html

new url´s:
http://mydomain/travelforum-id5665.html
http://mydomain/travelforum-id5665-post12.html
and so on...

I want to permanent redirect (301) old urls to new url´s
but the problem is that they have prameters
How can I do this?

thanks a lot

 

There is no way to do this?

 

Can you post the contents of your current .htaccess file? It should just be a case of adding the extra "travel" keyword into it.

 

I don´t want to add more rewrites, I just want to redirect
this:
http://mydomain/forum-id5665-post12.html
to this:
http://mydomain/travelforum-id5665-post12.html

but the proble is that 5665 and 12 are parameters so they change

 

RedirectMatch 301 ^/forum\-(.*)\.html$ http://domain.com/travelforum-$1.html
RedirectMatch 301 ^/forum\-(.*)\-(.*)\.html$ http://domain.com/travelforum-$1-$2.html

Code (markup):

Tell me if it works.

 

it doesn´t recognize the rule, error 404 Not Found
thank you anyway
