Tools

httptools provides the following tools:

Handler list

Define a sequence of http.Handler. One will be executed after another.

Silent handler

If a silent handler produces output, it is assumed to be an error. If the silent handler is in a handler list, the execution of that list will be aborted.

Switches

Method switch

Dispatch requests to different handlers according the the HTTP verb used in the request.

RegexpSwitch

Dispatch requests to different handlers according to regexps being matched against the request path.

HostnameSwitch

Dispatch requests to different handlers according to the hostname used in the request.

Mounts

Dispatch requests to different handlers according to path prefixes. The path prefix will be stripped from the request before being passed to the handler.
