[quote author="pistolPete" date="1227629786"]Either you could use .htaccess or the plain php header() function:

Code:

header( "HTTP/1.1 301 Moved Permanently" );
header("Location: http://www.sample.com/where_you_want_to_go");

If I use .htaccess how the syntax or maybe i can ask link about that and if I use php header() function where i set that code? Thx?
