+*ANNOUNCEMENT: If you like GCDWebServer, check out [XLFacility](https://github.com/swisspol/XLFacility), an elegant and powerful logging facility for OS X & iOS by the same author and also open-source. XLFacility can be used seemlessly to handle logging from GCDWebServer (see "Custom Logging" below).*

 GCDWebServer is a modern and lightweight GCD based HTTP 1.1 server designed to be embedded in OS X & iOS apps. It was written from scratch with the following goals in mind:
 * Elegant and easy to use architecture with only 4 core classes: server, connection, request and response (see "Understanding GCDWebServer's Architecture" below)
 * Well designed API with fully documented headers for easy integration and customization

 Debug Builds & Custom Logging
 =============================
 
-When building GCDWebServer in "Debug" mode versus "Release" mode, GCDWebServer logs a lot more information and also performs a number of internal consistency checks. To enable this behavior, define the preprocessor constant ```DEBUG=1``` when compiling GCDWebServer. In Xcode target settings, this can be done by adding ```DEBUG=1``` to the build setting ```GCC_PREPROCESSOR_DEFINITIONS``` when building in Debug configuration.

 It's also possible to replace the logging system used by GCDWebServer by a custom one. Simply define the preprocessor constant ```__GCDWEBSERVER_LOGGING_HEADER__``` to the name of a header file (e.g. "MyLogging.h") that defines these macros:
