When implementing an HTTP filter, the idea is not to process the request, but to modify and redirect the request. With respect to the HTTP protocol, there are two ways to trigger an HTTP filter: URL and HTTP header. It is possible to trigger an HTTP filter based on some piece of data sent to or generated by the server in the HTTP body. For example, in the state sent to the server, there could be a keyword indicating further actions for the HTTP filter. But using a piece of data in the HTTP body itself is a bad idea because it requires extra processing by the server. The data in the HTTP body is specific to the HTTP handler and should be considered as a single entity. This does not mean that an HTTP filter, after it has been triggered, cannot inspect and manipulate the payload. What this means is that for trigger purposes only, the URL or HTTP header is inspected. Let s go through the differences of URL vs. HTTP header by using the State Navigation pattern as an example. In the section Managing State at the Protocol Level, an HTTP header is used to request a state that is associated with a URL, as illustrated by the following HTTP request part: java qr code Java QR Code - Javapapers

It allows for the management of role-based authorization //visible public function get visible():Boolean { return _visible; } public function set visible(value:Boolean):void { _visible = value; dispatchEvent(new Event(Event.CHANGE)); } //rotationValue public function get rotationValue():Number { return _rotationValue; } public function set rotationValue(value:Number):void { _rotationValue = value; if(_rotationValue > 360) { _rotationValue = 0; } } } } Note that the frictionConstant property was not created as a true constant because it could change during the game. java qr code Java : Simple QR Code Generator Example - Now you Could have ...

The Security Application Block supplies an AzMan provider to easily determine if users are authorized for a specific task or operation based on information contained in their identity. The AzManAuthorizationProvider class allows the use of Windows Server 2003 AzMan within the Security Application Block. To use the AzManAuthorizationProvider class, you need to install the Windows Server 2003 Administration Tools Pack for Windows XP and Windows 2003 computers. Windows Vista should install AzMan by default. The other authorization provider class is AuthorizationRuleProvider. The AuthorizationRuleProvider class allows a rule to be defined for each task, to specify which roles and identities are authorized. It uses a logical equation type of syntax to describe a rule. java qr code reader example New QR Code Reader Library - DZone Mobile

GET /ajax/chap07/page1/state HTTP/1.1 Accept: application/ajax-state Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 X-Page-Window-Name: window-2005-10-03-10-10-10-1245 X-Page-State: none The request has two pieces of information that could trigger a filter: URL ([url]/state) and HTTP header (X-Page-State). To trigger a filter via a URL, the URL must be processed. Processing a URL is a relatively expensive step and potentially buggy. The bugginess results when a URL has the same text as a trigger. The header is necessary only when the state is retrieved, and that occurs only when the XMLHttpRequest object is used. Thus adding an HTTP header is not complicated or inconvenient. Which solution you use depends on your URLs and what you are comfortable with. The rule of thumb is that an HTTP header can be used when both the client and the server are capable of processing the custom header, and a URL should be used whenever the server knows what kind of client will process the data. When implementing an HTTP filter, a basis class that executes the trigger and runs the filter action is illustrated by using the following Java filter code. On other platforms and programming languages, the code will be similar because other platforms also have the concept of an HTTP filter. You can see that this is a typical model class. It s a data storage object, with a specific method called update that helps process that data. You can tell it s an abstract class because of the uppercase A in the class name and the comment to remind you to not instantiate it. //ABSTRACT CLASS - Do not instantiate public class AVerletModel extends EventDispatcher { One thing that s different from the model classes that we looked at in the previous two chapters is that the update method fires an "update" event. dispatchEvent(new Event("update")); This is important because sometimes your games will need to know exactly when a model is being updated, without needing to be informed of other CHANGE events. You ll see some examples of how this event is used in the chapters ahead. Authenticating a user often requires calls to resources that are not locally available. In a stateless environment, a user should be verified every time a request is made to the server. Unfortunately, these two conditions together can create a significant performance overhead. The solution that the Security Application Block provides is to use a security cache for caching credentials, and supply clients with a token that they can present as proof that they have been authenticated. This local cache then expedites credential retrieval. qr code reader java app BeeTagg QR Reader for Java (en)
