+/**
+ *  GCDWebServer provides its own built-in logging facility which is used by
+ *  default. It simply sends log messages to stderr assuming it is connected
+ *  to a terminal type device.
+ *
+ *  GCDWebServer is also compatible with a limited set of third-party logging
+ *  facilities. If one of them is available at compile time, GCDWebServer will
+ *  automatically use it in place of the built-in one.
+ *
+ *  Currently supported third-party logging facilities are:
+ *  - XLFacility (by the same author as GCDWebServer): https://github.com/swisspol/XLFacility
+ *
+ *  For the built-in logging facility, the default logging level is INFO
+ *  (or DEBUG if the preprocessor constant "DEBUG" evaluates to non-zero at
+ *  compile time).
+ *
+ *  It's possible to have GCDWebServer use a custom logging facility by defining
+ *  the "__GCDWEBSERVER_LOGGING_HEADER__" preprocessor constant in Xcode build
+ *  settings to the name of a custom header file (escaped like \"MyLogging.h\").
+ *  This header file must define the following set of macros:
+ *
+ *    GWS_LOG_DEBUG(...)
+ *    GWS_LOG_VERBOSE(...)
+ *    GWS_LOG_INFO(...)
+ *    GWS_LOG_WARNING(...)
+ *    GWS_LOG_ERROR(...)
+ *
+ *  IMPORTANT: These macros must behave like NSLog(). Furthermore the GWS_LOG_DEBUG()
+ *  macro should not do anything unless the preprocessor constant "DEBUG" evaluates
+ *  to non-zero.
+ *
+ *  The logging methods below send log messages to the same logging facility
+ *  used by GCDWebServer. They can be used for consistency wherever you interact
+ *  with GCDWebServer in your code (e.g. in the implementation of handlers).

 Getting Started
 ===============
 
 Download or check out the [latest release](https://github.com/swisspol/GCDWebServer/releases) of GCDWebServer then add the entire "GCDWebServer" subfolder to your Xcode project. If you intend to use one of the extensions like GCDWebDAVServer or GCDWebUploader, add these subfolders as well.
 
-Alternatively, you can install GCDWebServer using [CocoaPods](http://cocoapods.org/) by simply adding this line to your Xcode project's Podfile:
+If you add the files directly then (1) link to `libz` (via Target > Build Phases > Link Binary With Libraries) and (2) add `$(SDKROOT)/usr/include/libxml2` to your header search paths (via Target > Build Settings > HEADER_SEARCH_PATHS).
+
+Alternatively, you can install GCDWebServer using [CocoaPods](http://cocoapods.org/) by simply adding this line to your Podfile:
 ```
-pod "GCDWebServer", "~> 2.0"
+pod "GCDWebServer", "~> 3.0"
 ```
 If you want to use GCDWebUploader, use this line instead:
 ```
-pod "GCDWebServer/WebUploader", "~> 2.0"
+pod "GCDWebServer/WebUploader", "~> 3.0"
 ```
 Or this line for GCDWebDAVServer:
 ```
-pod "GCDWebServer/WebDAV", "~> 2.0"
+pod "GCDWebServer/WebDAV", "~> 3.0"
 ```
 
+And finally run `$ pod install`.
+
+You can also use [Carthage](https://github.com/Carthage/Carthage) by adding this line to your Cartfile (3.2.5 is the first release with Carthage support):
+```
+github "swisspol/GCDWebServer" ~> 3.2.5
+```
+
+Then run `$ carthage update` and add the generated frameworks to your Xcode projects (see [Carthage instructions](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application)).
+
+Help & Support
+==============
+
+For help with using GCDWebServer, it's best to ask your question on Stack Overflow with the [`gcdwebserver`](http://stackoverflow.com/questions/tagged/gcdwebserver) tag. For bug reports and enhancement requests you can use [issues](https://github.com/swisspol/GCDWebServer/issues) in this project.
+
+Be sure to read this entire README first though!

 Hello World
 ===========
 
 These code snippets show how to implement a custom HTTP server that runs on port 8080 and returns a "Hello World" HTML page to any request. Since GCDWebServer uses GCD blocks to handle requests, no subclassing or delegates are needed, which results in very clean code.
 
+**IMPORTANT:** If not using CocoaPods, be sure to add the `libz` shared system library to the Xcode target for your app.

+GCDWebServer relies on "handlers" to process incoming web requests and generating responses. Handlers are implemented with GCD blocks which makes it very easy to provide your own. However, they are executed on arbitrary threads within GCD so __special attention must be paid to thread-safety and re-entrancy__.
 
 Handlers require 2 GCD blocks:
 * The ```GCDWebServerMatchBlock``` is called on every handler added to the ```GCDWebServer``` instance whenever a web request has started (i.e. HTTP headers have been received). It is passed the basic info for the web request (HTTP method, URL, headers...) and must decide if it wants to handle it or not. If yes, it must return a new ```GCDWebServerRequest``` instance (see above) created with this info. Otherwise, it simply returns nil.
-* The ```GCDWebServerProcessBlock``` is called after the web request has been fully received and is passed the ```GCDWebServerRequest``` instance created at the previous step. It must return a ```GCDWebServerResponse``` instance (see above) or nil on error, which will result in a 500 HTTP status code returned to the client. It's however recommended to return an instance of [GCDWebServerErrorResponse](GCDWebServer/Responses/GCDWebServerErrorResponse.h) on error so more useful information can be returned to the client.
+* The ```GCDWebServerProcessBlock``` or ```GCDWebServerAsyncProcessBlock``` is called after the web request has been fully received and is passed the ```GCDWebServerRequest``` instance created at the previous step.

It's however recommended to return an instance of [GCDWebServerErrorResponse](GCDWebServer/Responses/GCDWebServerErrorResponse.h) on error so more useful information can be returned to the client.
 
-Note that most methods on ```GCDWebServer``` to add handlers only require the ```GCDWebServerProcessBlock``` as they already provide a built-in ```GCDWebServerMatchBlock``` e.g. to match a URL path with a Regex.

+
+Asynchronous HTTP Responses
+===========================
+
+New in GCDWebServer 3.0 is the ability to process HTTP requests asynchronously i.e. add handlers to the server which generate their ```GCDWebServerResponse``` asynchronously. This is achieved by adding handlers that use a ```GCDWebServerAsyncProcessBlock``` instead of a ```GCDWebServerProcessBlock```. Here's an example:
+
+**(Synchronous version)** The handler blocks while generating the HTTP response:
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                         processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {
+  
+  GCDWebServerDataResponse* response = [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];
+  return response;
+  
+}];
+```
+
+**(Asynchronous version)** The handler returns immediately and calls back GCDWebServer later with the generated HTTP response:
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                    asyncProcessBlock:^(GCDWebServerRequest* request, GCDWebServerCompletionBlock completionBlock) {
+  
+  // Do some async operation like network access or file I/O (simulated here using dispatch_after())
+  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+    GCDWebServerDataResponse* response = [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];
+    completionBlock(response);
+  });
+
+}];
+```
+
+**(Advanced asynchronous version)** The handler returns immediately a streamed HTTP response which itself generates its contents asynchronously:
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                         processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {
+  
+  NSMutableArray* contents = [NSMutableArray arrayWithObjects:@"<html><body><p>\n", @"Hello World!\n", @"</p></body></html>\n", nil];  // Fake data source we are reading from
+  GCDWebServerStreamedResponse* response = [GCDWebServerStreamedResponse responseWithContentType:@"text/html" asyncStreamBlock:^(GCDWebServerBodyReaderCompletionBlock completionBlock) {
+    
+    // Simulate a delay reading from the fake data source
+    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+      NSString* string = contents.firstObject;
+      if (string) {
+        [contents removeObjectAtIndex:0];
+        completionBlock([string dataUsingEncoding:NSUTF8StringEncoding], nil);  // Generate the 2nd part of the stream data
+      } else {
+        completionBlock([NSData data], nil);  // Must pass an empty NSData to signal the end of the stream
+      }
+    });
+    
+  }];
+  return response;
+  
+}];
+```
+
+*Note that you can even combine both the asynchronous and advanced asynchronous versions to return asynchronously an asynchronous HTTP response!*
 
 GCDWebServer & Background Mode for iOS Apps
 ===========================================
@@ -220,6 +358,17 @@ Fortunately, GCDWebServer does all of this automatically for you:
 
 HTTP connections are often initiated in batches (or bursts), for instance when loading a web page with multiple resources. This makes it difficult to accurately detect when the *very last* HTTP connection has been closed: it's possible 2 consecutive HTTP connections part of the same batch would be separated by a small delay instead of overlapping. It would be bad for the client if GCDWebServer suspended itself right in between. The ```GCDWebServerOption_ConnectedStateCoalescingInterval``` option solves this problem elegantly by forcing GCDWebServer to wait some extra delay before performing any action after the last HTTP connection has been closed, just in case a new HTTP connection is initiated within this delay.
 
+Logging in GCDWebServer
+=======================
+
+Both for debugging and informational purpose, GCDWebServer logs messages extensively whenever something happens. Furthermore, when building GCDWebServer in "Debug" mode versus "Release" mode, it logs even more information but 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. Finally, you can also control the logging verbosity at run time by calling ```+[GCDWebServer setLogLevel:]```.
+
+By default, all messages logged by GCDWebServer are sent to its built-in logging facility, which simply outputs to ```stderr``` (assuming a terminal type device is connected). In order to better integrate with the rest of your app or because of the amount of information logged, you might want to use another logging facility.
+
+GCDWebServer has automatic support for [XLFacility](https://github.com/swisspol/XLFacility) (by the same author as GCDWebServer and also open-source): if it is in the same Xcode project, GCDWebServer should use it automatically instead of the built-in logging facility (see [GCDWebServerPrivate.h](GCDWebServer/Core/GCDWebServerPrivate.h) for the implementation details).
+
+It's also possible to use a custom logging facility - see [GCDWebServer.h](GCDWebServer/Core/GCDWebServer.h) for more information.
