Hi
I have a number of domains pointing to the same IP and we are serving
almost similar content on all domains (a few minor differences in the
visual outlay etc are ensured using a PHP backend to serve content).
However it seems google does not take kindly to such practices and
recently the primary domain has been removed from the google index.
This primary domain's homepage enjoyed a PR 5 and had more than 50,000
pages indexed on Google. In another post, I was told that the multiple
domain system was the reason for this.

Is it possible that I use the .htaccess file to identify googlebot and
for all googlebot accesses to all URLs with the non-primary domain I
use mod_rewrite to ensure a 301 (Permanent) redirect to the the primary
domain.

1. I hope that will ensure that the non-primary domains are taken
off the google index.
2. Also, will this step of mine ensure that the primary domain is
restored on the google index?
3. Finally, do I need to, in some way, contact Google to have them
restore my site on the google index, after I have set up the 301
redirect for googlebot?

thanks
