<translate> Search engine friendly (SEF), human-readable or clean URLs are URLs that make sense to both humans and search engines because they explain the path to the particular page they point to. Since version 1.5, Joomla! is capable of creating and parsing URLs in any format, including SEF URLs. This does not depend on URL rewriting executed by the web server, so it works even if Joomla! runs a server other than Apache with the mod_rewrite module. The SEF URLs follow a certain fixed pattern, but the user can define a short descriptive text (alias) for each segment of the URL.
Internally, the local part of a SEF URL (the part after the domain name) is called a route. Creating and processing SEF URLs is therefore referred to as routing, and the relevant code is called a router. </translate>
This article addresses SEF URLs under the popular, open-source Apache webserver. SEF URL implementation is possible under Microsoft's IIS webserver as well, please see Enabling Search Engine Friendly (SEF) URLs on IIS.
Since Joomla! 1.6, basic SEF urls are enabled by default. In prior versions you need to use the Global Configuration to enable them. The instructions below still apply if you want to use Apache's mod_rewrite/URL rewriting.
These are step-by-step instructions. Please follow them in the order they are presented here. If a step fails, do not continue until you have solved the problem.
