![]() Returning the atom auto instead of a callback informs Cowboy that it needs to handle range requests automatically. This changes the behavior so that the ProvideCallback function is called and then Cowboy splits the data on its own and sends the response without any other user involvement other than defining the ranges_provided/2 callback. This is a quick and dirty way to add range request support to resources, and will be good enough for many cases including for cowboy_static as it also works when the normal response body is a sendfile tuple. |

= Cowboy Cowboy is a small, fast and modern HTTP server for Erlang/OTP. == Goals Cowboy aims to provide a *complete* HTTP stack in a *small* code base. It is optimized for *low latency* and *low memory usage*, in part because it uses *binary strings*. Cowboy provides *routing* capabilities, selectively dispatching requests to handlers written in Erlang. Because it uses Ranch for managing connections, Cowboy can easily be *embedded* in any other application. Cowboy is *clean* and *well tested* Erlang code. == Online documentation * https://ninenines.eu/docs/en/cowboy/2.5/guide[User guide] * https://ninenines.eu/docs/en/cowboy/2.5/manual[Function reference] == Offline documentation * While still online, run `make docs` * User guide available in `doc/` in PDF and HTML formats * Function reference man pages available in `doc/man3/` and `doc/man7/` * Run `make install-docs` to install man pages on your system * Full documentation in Asciidoc available in `doc/src/` * Examples available in `examples/` == Getting help * Official IRC Channel: #ninenines on irc.freenode.net * https://github.com/ninenines/cowboy/issues[Issues tracker] * https://ninenines.eu/services[Commercial Support]
