+/**
+ * In order to provide fast and flexible logging, this project uses Cocoa Lumberjack.
+ * 
+ * The Google Code page has a wealth of documentation if you have any questions.
+ * https://github.com/robbiehanson/CocoaLumberjack
+ * 
+ * Here's what you need to know concerning how logging is setup for CocoaHTTPServer:
+ * 
+ * There are 4 log levels:
+ * - Error
+ * - Warning
+ * - Info
+ * - Verbose
+ * 
+ * In addition to this, there is a Trace flag that can be enabled.
+ * When tracing is enabled, it spits out the methods that are being called.
+ * 
+ * Please note that tracing is separate from the log levels.
+ * For example, one could set the log level to warning, and enable tracing.
+ * 
+ * All logging is asynchronous, except errors.
+ * To use logging within your own custom files, follow the steps below.
+ * 
+ * Step 1:
+ * Import this header in your implementation file:
+ * 
+ * #import "HTTPLogging.h"
+ * 
+ * Step 2:
+ * Define your logging level in your implementation file:
+ * 
+ * // Log levels: off, error, warn, info, verbose
+ * static const int httpLogLevel = HTTP_LOG_LEVEL_VERBOSE;
+ * 
+ * If you wish to enable tracing, you could do something like this:
+ * 
+ * // Debug levels: off, error, warn, info, verbose
+ * static const int httpLogLevel = HTTP_LOG_LEVEL_INFO | HTTP_LOG_FLAG_TRACE;
+ * 
+ * Step 3:
+ * Replace your NSLog statements with HTTPLog statements according to the severity of the message.
+ * 
+ * NSLog(@"Fatal error, no dohickey found!"); -> HTTPLogError(@"Fatal error, no dohickey found!");
+ * 
+ * HTTPLog works exactly the same as NSLog.
+ * This means you can pass it multiple variables just like NSLog.

+/**
+ * Important notice to those implementing custom asynchronous and/or chunked responses:
+ * 
+ * HTTPConnection supports asynchronous responses.  All you have to do in your custom response class is
+ * asynchronously generate the response, and invoke HTTPConnection's responseHasAvailableData method.
+ * You don't have to wait until you have all of the response ready to invoke this method.  For example, if you
+ * generate the response in incremental chunks, you could call responseHasAvailableData after generating
+ * each chunk.  Please see the HTTPAsyncFileResponse class for an example of how to do this.
+ * 
+ * The normal flow of events for an HTTPConnection while responding to a request is like this:
+ *  - Send http resopnse headers
+ *  - Get data from response via readDataOfLength method.
+ *  - Add data to asyncSocket's write queue.
+ *  - Wait for asyncSocket to notify it that the data has been sent.
+ *  - Get more data from response via readDataOfLength method.
+ *  - ... continue this cycle until the entire response has been sent.
+ * 
+ * With an asynchronous response, the flow is a little different.
+ * 
+ * First the HTTPResponse is given the opportunity to postpone sending the HTTP response headers.
+ * This allows the response to asynchronously execute any code needed to calculate a part of the header.
+ * An example might be the response needs to generate some custom header fields,
+ * or perhaps the response needs to look for a resource on network-attached storage.
+ * Since the network-attached storage may be slow, the response doesn't know whether to send a 200 or 404 yet.
+ * In situations such as this, the HTTPResponse simply implements the delayResponseHeaders method and returns YES.
+ * After returning YES from this method, the HTTPConnection will wait until the response invokes its
+ * responseHasAvailableData method. After this occurs, the HTTPConnection will again query the delayResponseHeaders
+ * method to see if the response is ready to send the headers.
+ * This cycle will continue until the delayResponseHeaders method returns NO.
+ * 
+ * You should only delay sending the response headers until you have everything you need concerning just the headers.
+ * Asynchronously generating the body of the response is not an excuse to delay sending the headers.
+ * 
+ * After the response headers have been sent, the HTTPConnection calls your readDataOfLength method.
+ * You may or may not have any available data at this point. If you don't, then simply return nil.
+ * You should later invoke HTTPConnection's responseHasAvailableData when you have data to send.
+ * 
+ * You don't have to keep track of when you return nil in the readDataOfLength method, or how many times you've invoked
+ * responseHasAvailableData. Just simply call responseHasAvailableData whenever you've generated new data, and
+ * return nil in your readDataOfLength whenever you don't have any available data in the requested range.
+ * HTTPConnection will automatically detect when it should be requesting new data and will act appropriately.
+ * 
+ * It's important that you also keep in mind that the HTTP server supports range requests.
+ * The setOffset method is mandatory, and should not be ignored.
+ * Make sure you take into account the offset within the readDataOfLength method.
+ * You should also be aware that the HTTPConnection automatically sorts any range requests.
+ * So if your setOffset method is called with a value of 100, then you can safely release bytes 0-99.
+ * 
+ * HTTPConnection can also help you keep your memory footprint small.
+ * Imagine you're dynamically generating a 10 MB response.  You probably don't want to load all this data into
+ * RAM, and sit around waiting for HTTPConnection to slowly send it out over the network.  All you need to do
+ * is pay attention to when HTTPConnection requests more data via readDataOfLength.  This is because HTTPConnection
+ * will never allow asyncSocket's write queue to get much bigger than READ_CHUNKSIZE bytes.  You should
+ * consider how you might be able to take advantage of this fact to generate your asynchronous response on demand,
+ * while at the same time keeping your memory footprint small, and your application lightning fast.
+ * 
+ * If you don't know the content-length in advanced, you should also implement the isChunked method.
+ * This means the response will not include a Content-Length header, and will instead use "Transfer-Encoding: chunked".
+ * There's a good chance that if your response is asynchronous and dynamic, it's also chunked.
+ * If your response is chunked, you don't need to worry about range requests.

+ *   If 1KB of data has been read from the file, but none of that data has yet been returned to the connection,
+ *   then the fileOffset variable remains at zero.
+ *   This variable is used in the calculation of the isDone method.
+ *   Only after all data has been returned to the connection are we actually done.
+ * 
+ * readOffset
+ *   Represents the offset of the file descriptor.
+ *   In other words, the file position indidcator for our read stream.
+ *   It might be easy to think of it as the total number of bytes that have been read from the file.
+ *   However, this isn't entirely accurate, as the setOffset: method may have caused us to
+ *   jump ahead in the file (lseek).
+ * 
+ * readBuffer
+ *   Malloc'd buffer to hold data read from the file.
+ * 
+ * readBufferSize
+ *   Total allocation size of malloc'd buffer.
+ * 
+ * readBufferOffset
+ *   Represents the position in the readBuffer where we should store new bytes.
+ * 
+ * readRequestLength
+ *   The total number of bytes that were requested from the connection.
+ *   It's OK if we return a lesser number of bytes to the connection.
+ *   It's NOT OK if we return a greater number of bytes to the connection.
+ *   Doing so would disrupt proper support for range requests.
+ *   If, however, the response is chunked then we don't need to worry about this.
+ *   Chunked responses inheritly don't support range requests.

+ * This class is designed to assist with dynamic content.
+ * Imagine you have a file that you want to make dynamic:
+ * 
+ * <html>
+ * <body>
+ *   <h1>ComputerName Control Panel</h1>
+ *   ...
+ *   <li>System Time: SysTime</li>
+ * </body>
+ * </html>
+ * 
+ * Now you could generate the entire file in Objective-C,
+ * but this would be a horribly tedious process.
+ * Beside, you want to design the file with professional tools to make it look pretty.
+ * 
+ * So all you have to do is escape your dynamic content like this:
+ * 
+ * ...
+ *   <h1>%%ComputerName%% Control Panel</h1>
+ * ...
+ *   <li>System Time: %%SysTime%%</li>
+ * 
+ * And then you create an instance of this class with:
+ * 
+ * - separator = @"%%"
+ * - replacementDictionary = { "ComputerName"="Black MacBook", "SysTime"="2010-04-30 03:18:24" }
+ * 
+ * This class will then perform the replacements for you, on the fly, as it reads the file data.
+ * This class is also asynchronous, so it will perform the file IO using its own GCD queue.
+ * 
+ * All keys for the replacementDictionary must be NSString's.
+ * Values for the replacementDictionary may be NSString's, or any object that
+ * returns what you want when its description method is invoked.

+
+CocoaHTTPServer is a small, lightweight, embeddable HTTP server for Mac OS X or iOS applications.
+
+Sometimes developers need an embedded HTTP server in their app. Perhaps it's a server application with remote monitoring. Or perhaps it's a desktop application using HTTP for the communication backend. Or perhaps it's an iOS app providing over-the-air access to documents. Whatever your reason, CocoaHTTPServer can get the job done. It provides:
+
+-   Built in support for bonjour broadcasting
+-   IPv4 and IPv6 support
+-   Asynchronous networking using GCD and standard sockets
+-   Password protection support
+-   SSL/TLS encryption support
+-   Extremely FAST and memory efficient
+-   Extremely scalable (built entirely upon GCD)
+-   Heavily commented code
+-   Very easily extensible
+-   WebDAV is supported too!
+

+/**
+ * Welcome to CocoaLumberjack!
+ *
+ * The project page has a wealth of documentation if you have any questions.
+ * https://github.com/CocoaLumberjack/CocoaLumberjack
+ *
+ * If you're new to the project you may wish to read "Getting Started" at:
+ * Documentation/GettingStarted.md
+ *
+ * Otherwise, here is a quick refresher.
+ * There are three steps to using the macros:
+ *
+ * Step 1:
+ * Import the header in your implementation or prefix file:
+ *
+ * #import <CocoaLumberjack/CocoaLumberjack.h>
+ *
+ * Step 2:
+ * Define your logging level in your implementation file:
+ *
+ * // Log levels: off, error, warn, info, verbose
+ * static const DDLogLevel ddLogLevel = DDLogLevelVerbose;
+ *
+ * Step 2 [3rd party frameworks]:
+ *
+ * Define your LOG_LEVEL_DEF to a different variable/function than ddLogLevel:
+ *
+ * // #undef LOG_LEVEL_DEF // Undefine first only if needed
+ * #define LOG_LEVEL_DEF myLibLogLevel
+ *
+ * Define your logging level in your implementation file:
+ *
+ * // Log levels: off, error, warn, info, verbose
+ * static const DDLogLevel myLibLogLevel = DDLogLevelVerbose;
+ *
+ * Step 3:
+ * Replace your NSLog statements with DDLog statements according to the severity of the message.
+ *
+ * NSLog(@"Fatal error, no dohickey found!"); -> DDLogError(@"Fatal error, no dohickey found!");
+ *
+ * DDLog works exactly the same as NSLog.
+ * This means you can pass it multiple variables just like NSLog.
