+HttpRouter is a lightweight high performance HTTP request router (also called *multiplexer* or just *mux* for short) for [Go](https://golang.org/).
 
 In contrast to the [default mux][http.ServeMux] of Go's `net/http` package, this router supports variables in the routing pattern and matches against the request method. It also scales better.

 **Only explicit matches:** With other routers, like [`http.ServeMux`][http.ServeMux], a requested URL path could match multiple patterns. Therefore they have some awkward pattern priority rules, like *longest match* or *first registered, first matched*. By design of this router, a request can only match exactly one or no route. As a result, there are also no unintended matches, which makes it great for SEO and improves the user experience.
 
-**Stop caring about trailing slashes:** Choose the URL style you like, the router automatically redirects the client if a trailing slash is missing or if there is one extra. Of course it only does so, if the new path has a handler. If you don't like it, you can [turn off this behavior](http://godoc.org/github.com/julienschmidt/httprouter#Router.RedirectTrailingSlash).

 **Path auto-correction:** Besides detecting the missing or additional trailing slash at no extra cost, the router can also fix wrong cases and remove superfluous path elements (like `../` or `//`).

HttpRouter can help him by making a case-insensitive look-up and redirecting him to the correct URL.

 **No more server crashes:** You can set a [Panic handler][Router.PanicHandler] to deal with panics occurring during handling a HTTP request. The router then recovers and lets the `PanicHandler` log what happened and deliver a nice error page.
 
-Of course you can also set **custom [`NotFound`][Router.NotFound] and  [`MethodNotAllowed`](http://godoc.org/github.com/julienschmidt/httprouter#Router.MethodNotAllowed) handlers** and [**serve static files**][Router.ServeFiles].

 ## How does it work?
 
-The router relies on a tree structure which makes heavy use of *common prefixes*, it is basically a *compact* [*prefix tree*](http://en.wikipedia.org/wiki/Trie) (or just [*Radix tree*](http://en.wikipedia.org/wiki/Radix_tree)). Nodes with a common prefix also share a common parent. Here is a short example what the routing tree for the `GET` request method could look like:

 ## Where can I find Middleware *X*?
 
-This package just provides a very efficient request router with a few extra features. The router is just a [`http.Handler`][http.Handler], you can chain any http.Handler compatible middleware before the router, for example the [Gorilla handlers](http://www.gorillatoolkit.org/pkg/handlers). Or you could [just write your own](http://justinas.org/writing-http-middleware-in-go/), it's very easy!
