Synchronous or asynchronous http request

Answer 3

In htaccess site1 add

RewriteEngine On
RewriteCond %{HTTP_HOST} ^site1.com
RewriteRule ^(.*) http://site2.com/$1 [P]

PS If it didn't take off, then it crashes with the 500th error. Also check that mod_rewrite , mod_proxy modules are enabled and mod_proxy_http just in case
