.htaccess - Don't spider certain pages on multiple domains same hosting -

i have hosting account 2 domains parked on it, websites shows different content reading domain being used.

google spider , list 2 domains different websites.

so have these listed on google:-
www.blue.com/index.php
www.pink.com/index.php

then lets have page want on blue domain: www.blue.com/test.php, domains parked still work @ www.pink.com/test.php

this means spidered, don't want do.

how can stop this?

is possible have multiple htaccess rules depending on domain? or maybe robots.txt stop spidering - how work multiple domains?

what best solution me?

redirect different domain specific robots_(blue|pink).txt in .htaccess:

<ifmodule mod_write.c>    rewriteengine on    # internal redirect robots_blue.txt   rewritecond %{http_host} =www.blue.com   rewriterule ^robots\.txt$ /robots_blue.txt [l]    # internal redirect robots_pink.txt   rewritecond %{http_host} =www.pink.com   rewriterule ^robots\.txt$ /robots_pink.txt [l]    # internal redirct index_blue.php, rewrite internal    rewritecond %{http_host} =www.blue.com   rewriterule ^index\.php$ /index_blue.php [l]  # or "... /index.php?site=blue"    # external permanent redirect of test.php index.php if not www.blue.com     rewritecond %{http_host} !=www.blue.com   rewriterule ^test\.php$ /index.php [l,r=301]     # internal redirect   rewritecond %{http_host} =www.pink.com   rewriterule ^index\.php$ /index_pink.php [l] 

robots_blue.txt, don't crawl test.php in www.blue.com:

user-agent: * sitemap: http://www.blue.com/sitemap.xml  disallow: /test.php disallow: ... 

robots_pink.txt, crawling allowed in www.pink.com:

user-agent: * sitemap: http://www.blue.com/sitemap.xml  disallow: 

if disallows of www.blue.com identical www.pink.com, use robots_blue.txt robots.txt both domains. should work if there no test.php used in www.pink.com.

but if sitemap.xml used in robots.txt should solution.
