-// it is assumed that the response is now completely sent.
-// Use HTTP_RESPONSE if it's the end of a response, and you want to start reading more requests afterwards.
-// Use HTTP_FINAL_RESPONSE if you wish to terminate the connection after sending the response.
-// 
-// If you are sending multiple data segments in a custom response, make sure that only the last segment has
-// the HTTP_RESPONSE tag. For all other segments prior to the last segment use HTTP_PARTIAL_RESPONSE, or some other
-// tag of your own invention.

-/**
- * 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.
