q1. why the hell someone would do that?
a1. if you bought some interesting domain like i do (heh heh) http://blog.ofhas.in and want your existing blog to be available there as well, without spending hours to move data and to give it same look-n-feel – here’s your time-saving wizard. and beside that, i also dont want to lose my existing blog but i just want to avoid the hassle of re-hosting/migrating 🙂
q2. oh really?? how can I do that?
a2. here you go
<?php
$dataurl =$primaryurl = "http://hasin.wordpress.com";//old domain
$secondaryurl = "http://blog.ofhas.in"; //new domain
$path =array_keys($_GET);
if(!empty($path[0])) $dataurl = "{$primaryurl}/{$path[0]}";
$data = file_get_contents($dataurl);
$pattern = "~{$primaryurl}/([\d\S\/]+)~";
$data = preg_replace($pattern,"{$secondaryurl}/$1",$data);
$data = str_replace(array("<a href=\"{$primaryurl}","<form action=\"{$secondaryurl}"),array("<a href=\"{$secondaryurl}","<form action=\"{$primaryurl}"),$data);
echo $data;
?>
q3. is that all?
a3. nope, you need to modify/write .htaccess file in the root of this new domain
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{QUERY_STRING} (.+)
RewriteRule ^(.*)$ index.php?$1&%{QUERY_STRING}
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1
this script will also change the urls of all your post and pagination, behaves exactly same as you have hosted your blog in this new url. only drawback is submitting a comment will take you to your original domain, but you can easily fix that but simulating a POST request using curl/stream wrapper/fopen. there is one more vital drawback which is you may lose some IP specific traffic data
have a look at my actual blog http://hasin.wordpress.com and new one at http://blog.ofhas.in
happy weekend!
