Aim:
==============================
to rewrite ALL the URL from:

http://www.fromdomain.com/ANYCAT/ANYFILE
to:
http://www.todomain.com/ANYCAT/ANYFILE

There is SOME files and category need to be excluded.
such as:

http://www.fromdomain.com/admin/
should also keep as:
http://www.fromdomain.com/admin/
without any changes.
so that we can still access

http://www.fromdomain.com/admin/

Please notice that we DO NOT want redirect, as we want to keep google index for sometime.

I am not sure if there is penalty in the google index.

if you are SEO expert, please advise.

as we have few domains and want to integrate it in ONE domain only.

Payment:
==============================
100% in escrow, .htaccess file need to send to us and test in our server:
RH 5, apache 2.x

if working good, we will complete the payment.

time limit, i guess less than 30 mins....
as we already have one similar .htaccess
but just want to seek for a better solution.
