301 Redirects mod_rewrite

Hi i am a complete noob when it comes to apache and really would appreciate any help i can get.

I am about to move a site from example.com to example.com.au it has 1600 pages indexed in google and was hoping not to have to write a rule for each page rather appened the .au to any request for that domain simmilar to a www.

is it possible to do somthing simmiarl to the code below to add a .au to the domain name

thanks in advanced
Cheers
Nick

# For sites running on a port other than 80
RewriteCond %{HTTP_HOST}   !^www\.example\.com [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteCond %{SERVER_PORT} !^80$
RewriteRule ^/(.*)         http://www.example.com:%{SERVER_PORT}/$1 [L,R]

# And for a site running on port 80
RewriteCond %{HTTP_HOST}   !^www\.example\.com [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteRule ^/(.*)         http://www.example.com/$1 [L,R]

Hi Nick,

Here is a .htaccess file that does what you want.

AddHandler cgi-script .cgi
#AddType application/x-httpd-cgi .cgi .pl
#Options +Indexes +ExecCGI
#DirectoryIndex index.cgi
#AllowOverride Limit FileInfo Indexes

RewriteEngine On
RewriteCond %{HTTP_HOST} ^example.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.example.com$
RewriteRule ^(.*)$ "http\:\/\/www\.example\.com\.au\/$1" [R=301,L]

Code (markup):

This also redirects the non-www to www but if you don't want this you can remove the [OR] RewriteCond %{HTTP_HOST} ^www.example.com$ part
