Database driven routes in CodeIgniter

[eluser]Clooner[/eluser]
I use also a form of database driven routes in my CI site and it works really straight forward with no speed loss what so ever. It uses only a couple of lines of code.

It doesn't use hooks or hacks into the system and it uses the standard AR from CI.

In my router file I check if a file exists. If it doesn't exist it uses the default routes which in all cases forwards you to a controller which generates an array from the database. This array contains the routing information. This array is then saved in a cache file. The controller redirects itself and next time the router is accessed the cache file is loaded. The cache file is updated once a day.

Simple, Effective and no speed loss.
