![]() Changes include: * Much simplified route configuration. * Etag generation is now enabled by default. * Web mimetypes are now detected by default. A bigger list of mimetypes can be detected without any additional library. * Mimetypes can no longer be specified as a list. Copying this list for new connections is too costy. You can easily convert it into a function and pass that function to the handler instead. * You can however specify a single hardcoded mimetype. Mostly useful when serving a single file, like an index.html file, to avoid extra operations. * Specifying a path as a list of tokens is not possible anymore. Use either a binary or a string. * Using a private directory will not work if the application was not started properly. Cowboy will not attempt to find the location of this directory if the VM doesn't know it, as this caused issues in some setups. * Overall the code has been much simplified and clarified, and of course has now been documented. |

Cowboy
Cowboy is a small, fast and modular HTTP server written in Erlang.
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 parts 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.
No parameterized module. No process dictionary. Clean Erlang code.
Sponsors
The SPDY protocol development is sponsored by LeoFS Cloud Storage.
