AceSEF offers 3 type of URL rewriting:

1. AceSEF Extension (recommended)
2. Joomla!  1.5 router.php file written by proper component developers
3. AceSEF basic rewriting

You are free to choose the router that suits you.




When we install any extension router it will be directed automatically to AceSEF extension router type (the recommended one). Joomla! 1.5 router file is written by proper component developers. We can also use AceSEF basic rewriting. By the way if we don't want to use AceSEF for any component we can select the last option and disable AceSEF for that component.

Skip prefix / menu
You can set a seperate prefix for each component here (instead of menu title) or you can skip totally menu title or prefix so URLs will start directly from the category title of the proper component.

Bypass Post redirects
When a web form is submitted to a server through an HTTP POST request, a web user that attempts to refresh the server response in certain user agents can cause the contents of the original HTTP POST request to be resubmitted, possibly causing undesired results, such as a duplicate web purchase.
