GlobalRedirect is a simple module which…

1. Checks the current URL for an alias and does a 301 redirect to it if it is not being used.
2. Checks the current URL for a trailing slash, removes it if present and repeats check 1 with the new request.
3. Checks if the current URL is the same as the site_frontpage and redirects to the frontpage if there is a match.
4. Checks if the Clean URLs feature is enabled and then checks the current URL is being accessed using the clean method rather than the 'unclean' method. (Currently only in DEV, will be in 1.3 soon)
