what is the easiest way to stealth forward this first.domain.com to second.domain.com? Been trying it with this codes in .htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^first.domain.com$
RewriteRule (.*)$ http://second.domain.com [R=301,L]
and
rewriteengine on
rewritecond %{REQUEST_URI} first.domain.com/
rewriterule (.*) http://second.domain.com [l,nc]
But I'm having no luck at all. I want to retain "first.domain.com" on my address bar even when the page is already on second.domain.com. Thanks in advance.
