 * \example uhttpd_tiny/httpd_tiny.c
 *
 * Minimalist HTTP server sample.
 *
 * This is a simple HTTP server based on the MicroHTTP library. It
 * should compile and run without modification on any operating system
 * that is supported by the MicroHTTP library.
 *
 * It does not include any redirection. Thus, it is required to specify
 * the full URL in the browser request, e.g. 127.0.0.1/index.html.
 *
 * Only a single server thread is running. Concurrent requests may
 * fail.
 *
 * When used on Nut/OS, make sure, that the macro NUT_OS has been
 * defined on the compile command, which can done by adding
 * HWDEF += -DNUT_OS
 * either in the Makefile or in app/UserConf.mk. It is further required,
 * that a valid network configuration exists in non-volatile memory. You
 * can run the sample application editconf to check this.
