DO NOT USE THIS PLUGIN! 
 It is outdated, not maintained and frankly there are better plugins to use.

bbRedirector makes it easy to redirect a page to another location using absolute urls from within WordPress. 
No mod_rewrite nor .htaccess is needed. You just create a page, add a specific customfield and choose the 
redirect template included with this plugin. It even allows you to set the required http status code (302 or 301). 
You can also set a default sitewide redirection or setup your own custom redirection.
The included templates should give you an easy start using this plugin.
