These examples were not designed with security in mind, but to show how the API can be used in principle. For more information, see the [documentation](https://github.com/civetweb/civetweb/tree/master/docs). Some examples can also be found in the [test](https://github.com/civetweb/civetweb/tree/master/test) folder (but they are less documented and adapted to the needs of the test framework). + +In addition, there is one example how to configure a HTTPS server, to comply with modern security standards ([https](https://github.com/civetweb/civetweb/tree/master/examples/https)). It does not hold any source, but only a configuration file and some documentation how to use it. + +Some no longer maintained examples can be found in the ["obsolete"](https://github.com/civetweb/civetweb/tree/master/examples/_obsolete) folder.
