Handling JavaScript Cookies

Cookies could become the ticket to success of a great JavaScript application. When cookies are properly defined, the application is stable and users will feel more secure because of the active monitoring and recording of the application. JavaScript would be able to seamlessly provide personalized services to users since cookies were already stored.

But as much as JavaScript cookies could be the tool for an effective Ajax based application, this could also be a ticket to disaster. If cookies are not properly used in the application, developers might build an application that are very susceptive to different form of attack.

JavaScript cookies are one of the small things that every developer should take care of seriously. They are usually the determining factor in terms of providing personalized services. The good news is they are relatively easier to implement so cookies can be set up in no time. But again, they should be properly implemented or else the application could be open to any type of attacks.

Working Both Ways

There are many forms of JavaScript cookies. But they could be differentiated through their storage target. The first type of JavaScript cookie is the type that is automatically stored in the user’s gadget. This is very useful for users since the cookie will have more information about the webpage so that they could be easily retrieved the next time they would visit the same webpage. The second type of JavaScript is the cookie that is automatically sent back to JavaScript for personalization of services.

This just means that the grasp of security and efficiency provided by cookies should be working in both ways. Creation of cookies and properly implementing it from the developer’s side is never enough.

Checking Cookies

The release of cookies should have an end point or else, the addition of cookies in the application is good for nothing. Aside from proper creation, developers should also make sure that the cookies are checked before they are properly admitted. This proper checking is implemented for two reasons: first, developers have to make sure that the cookies that requests for previously released data has the right credentials.

As already indicated, cookies are added to increase the security of the online application. The second reason for proper checking of cookies is to ensure JavaScript’s ability to continue the process. The problem about the inability of JavaScript’s response to the “back” button is the lack of implementation of cookies.

User Awareness

A unique feature in cookies is in its ability to be part of the user. While other functions are working as a background and will work even without the knowledge of the user, it is a highly recommended practice for developers to let the users be aware of the stored cookies. This is done to assure users that the website is legitimate and will only extract information required.

With proper implementation of cookies, developers will have highly interactive application without dragging the user to consistently request for new data as well as improve the website’s security and user protection.
