Session Tracking mechanisam in java servlets with examples

Session Tracking: We know that a protocol is a set of rules which are used for exchanging the data between client and server side applications.Session Tracking example,Session Tracking in java,Session Tracking techniques in java,Session Tracking mechanisam in servlets,Session Tracking in servlets ,Session Tracking in jsp,Session Tracking all techniques

1.       In the current internet world all the web applications are making use of a universal protocol called http.

2.      http is one of the stateless protocol. A stateless protocol is one which maintains an identity of a client for a limited period of time. In the real world servers development all the web and application servers uses http protocol. So that all application and web servers are treated as stateless servers.Session Tracking example,Session Tracking in java,Session Tracking techniques in java,Session Tracking mechanisam in servlets,Session Tracking in servlets ,Session Tracking in jsp,Session Tracking all techniques

3.      Stateless servers are by default treated every request of the same user as individual/fresh/new request that means if one internet user makes ‘n’ number of requests then all such requests are treated as individual/ new requests which is not a recommended process.

4.      In any web application development if client makes multiple requests then as a server side programmer we must maintain all such individual requests as consecutive requests by making use of Session Tracking techniques. For example if we make first request to the servlet which is running in the context of server then the following sequence of operations will be taken place

i)                    Server control comes to service(-,-)

ii)                  Server instance a thread, objects of HttpServletRequest and HttpServletResponse.

iii)                Server executes the request processing logic written in the service(-,-).

iv)                Server gives the result of the servlet as a response back to the client.

v)                  Once the response is given back to the client the server remove or deletes the thread and Rqequest and Response objects.

       Hence the same process is applicable to further sub sequent results and all the requests are treated as individual requests by the sever and even though multiple requests made by the same user. Hence the above points makes us to understand the real world  web and application servers does not having any memory.

       So by using the Session Tracking techniques which are available in the servlet API, As a servlet programmer for the real world servers we need to provide a short memory.

     In the Short memory of web or Application server, what are all multiple requests made by the client are treated as consecutive results.

Definition of Session Tracking: The mechanism of maintaining multiple individual requests of same user as consecutive/sequence of Requests is known as Session Tracking.

      In Servlet programming we have four Session Tracking techniques those are

i)                    Cookies

ii)                  Http Sessions

iii)                Hidden form fields

iv)                URL Rewritten

Java Flaw Repair Email Camouflages Crafty New Malware Attack

Hides Java Error Repair e-mail Crafty new attack malware:News Analysis: Java vulnerabilities announced in January that it was bad enough. Book Now, a new type of malware occurs when an update for Java, it is recorded that only adds more malicious destination.
Back in January, there was big news about a zero-day vulnerability in Java. Could this vulnerability allows Bad Guys software installed on your computer that allows them to (among others) into another machine on a zombie botnet. At that time, the recommendation that users disable Java in their browsers.
As you can imagine, Oracle, the company responsible for when it acquired Java Sun Microsystems took hastily fix worked. This fix is ​​now available and you can download. Direct the attention to the new Java vulnerability led to a new approach of malware is as a solution to the vulnerability.
As it happens. New malware appears on the screen and look for the most obvious as the default window Java update and requests permission to install updates. The Java logo is, and if you're not careful, it seems legitimate. Click to order and give it permission to install malware instead of updating.
"Java Security is a kind of social engineering," said Kevin Haley, director of Symantec Security Response. "This is not a vulnerability, it's just a way to get people to click on the attachment."

Fortunately, if you have enough to ensure the safety will not really do anything, even if you give permission for the "Update". Unfortunately, there is no way to know for sure that the security prisoners. It all depends on what kind of security software you are running, and how long it has been updated. "Do you consider yourself infected shoulds," said Haley.
Haley said that Symantec provides free security scanning services that can be checked for malware, and he said that many other similar security services. These products, which you download and install on your computer, Windows, will give a full scan malware and alert you to any viruses or other malicious software. You can find this item scanning software, McAfee and Kaspersky among others.
Haley said he was surprised by the appearance of fake update Java. "There is always the former which is a zero-day vulnerability in case the thesis propaganda" Haley said. "It is in the public domain, all the bad guys want to use it. There race between patches and exploits."
The problem is much worse, Que La recent hacking kits Took it to become commercial. "These guys compete to sell their tools the bad guys," said Haley. "We see them in the field faster. You are not lying then it was before people start weak thesis."

Especially effective update the form of social engineering for people trying to spread malicious programs, simply because people are used to using almost as a reflex. Haley Symantec said that even mass e-mail claiming to be from the company containing counterfeit Symantec This update malware found.
"Do not click on attachments," said Haley, and he warned against visiting sites that you do not know is malware Fri Fortunately, most is security software, you can find sites with malware scanning and warn you or prevent you from going there.
Haley aussi noted that the major anti-virus software is not enough. He said que le Moyen distributing malware has changed, and now it's your safety should recognize attacks from a number of sources, not just viruses. Haley aussi suggest that you remove the application from your computer every fact that you do not use. "Get them out of the system, so unless you have a vulnerability." He advised aussi removal of normal data protection on mobile devices, devices Android, in particular. "We're seeing malware on Android is not the root of the device -., Which opened for malware."
"Rooting" means clustering defeating the security features built into the mobile device, que le owner can take control of the great features in the field of ICT. This goal aussi easier hackers to seize control of the remote device to take the land of malware.
