.htaccess help, not working when I changed servers

I am not very familiar with .htaccess and have already searched through the net but couldn't find an explanation to what I have

RewriteEngine On
DirectoryIndex index.php
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?mpage=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?mpage=$1
RewriteRule ^search-result/([^/\.]+)$ index.php?mpage=search-result&subpage=$1  [L]
RewriteRule ^search-result/([^/\.]+)/(.*)$ index.php?mpage=search-result&subpage=$1&act=$2 [L]
RewriteRule ^online-result/([^/\.]+)$ index.php?mpage=online-result&subpage=$1  [L]
RewriteRule ^online-result/([^/\.]+)/(.*)$ index.php?mpage=online-result&subpage=$1&act=$2 [L]

This is an .htaccess to what I am building, this worked before on a GoDaddy server but when changed server, it wont work any more.

Let say http://www.mywebsite.com/home worked before, because if you can see mpage=$1 it replaces the 开发者_如何学Cget to the one on slash right? But when I change servers it will see a 404 error.

Any ideas what it could be?

make sure you have the apache rewrite module enabled, and that AllowOverride is set to All in your vhost config
