.htaccess - redirectmatch changes post to get

Question

I have two separated vhost. On the www. one, I have instaled this only line on .htaccess

redirectMatch 301 ^(.*)$ http://d_blur_blur_s.com$1

All works as expected except that in the case where the POST is converted to GET.
Please notice that the post has parametres as a get (i didn't do it, and I won't change it) i am just trying to avoid duplicated content. I am showing firebug trace.

I expect to have the POST redirected on the main domain with redirectmatch or other trick.

Update
I have half of the internal links on the site written with www and the other half without it. So I need to keep both public but not duplicated. I need the GETs forwarded as GETs and the POSTs frowarded as POSTs. the problem is big, I have 12000 pages indexed, and lot of forms. So I am first searching for a generic solution without changing code. I full control de server.

Thanks a lot

You redirect using 307 instead of 301 to keep the post data, but some browsers show a dialog to the user if he is sure he want to sent the post data, so not real pretty.

But I'd rather go and fix the problem at the root. The only way you would get a post to the wrong domain is if the html-form refers to the wrong domain (e.g. <form action="www.d_blur_blur_s/public/main/loginGenerator.php" ...). Just fix the html.

Don't worry about duplicated content as search engines never send post-requests, only get. You current solution should do the trick to prevent duplicated content.
