NetScaler is one of the known applications that are frequently used in website development. It works by improving the user’s experience of accessing data from the website. If the website also works as an online application, NetScaler also has the ability to improve the uptime of the application. Combining data and application availability, NetScaler could virtually support the website by itself. Maintenance of the website is easier with NetScaler. Although NetScaler has been developed years earlier before Ajax is released, it is actually a very efficient product for an Ajax based website. To fully understand how NetScaler works in Ajax, we have to take a look at the data process of Ajax. Unlike simple HTML based websites, Ajax efficiently accesses data and makes them available for the customer without refreshing the whole webpage. When Ajax is efficiently rendered in the website, users could easily access the information using lesser bandwidth. The challenge of any Ajax developer is the ability to optimize the information that the users can access. This is where NetScaler comes in. NetScaler creates multiple connections that reduce the process of accessing information. Instead of using a single line of connection, they created multiple lines so that they can access small chunks of information and render them in the webpage as a whole. NetScaler calls the program as the NetScaler Request Switching. Aside from properly rendering the information to webpage efficiently, caching in Ajax has been harnessed by NetScaler. Caching is quiet a challenge in Ajax since it could overload the website when loaded in IE browsers. NetScaler cleverly used caching of the website for Ajax by caching only the first page of the website. That means everything will be rendered from the server. Instead of constantly referring from the server from the whole webpage, the initial page has been cached so that it could easily be available for the user. Think of it as temporarily storing the whole framework of the webpage and everything else has to be accessed from the server. It will definitely load faster since it doesn’t access the server for maintaining the whole webpage instead it uses the temporary folder and uses the server for user input. This is also important when Ajax based website is being used as an online tool. Instead of loading the whole tool each time the tool it is being used, the tool is already preloaded. All it needs is the command to make it work. There are many additional results that you can expect from that feature alone of NetScaler. Because the information is being accessed in small scale instead of being rendered once, the server is virtually protected from request overload. Query to the server when placed in limited value is easier compared to large scale requests. Security could also be emphasized since requests could be screened more. As a tool for web development, NetScaler has again established itself as a leader in web development. Thinking of new ways to enhance the webpage and ultimately user experience, NetScaler will maintain the webpage and the server better even in HTML based webpage.
