Perhaps you have seen how the feel of the web is changing? Perhaps you use LinkedIn - http://www.linkedin.com or Jobster - http://www.jobster.com and very probably youve had a look at routes - http://maps.google.com/ If thats the case you cant but have noticed that these sites and others have another look and feel. Its perhaps not about but about the way they seem faster and easier to use. A lot of sites are slow and tedious giving you the impression thatyou have sufficient time to acquire a coffee or even go to lunch. Its the hour-glass. You click a link and the hourglass appears because the site contacts the server and the server ponders what its going to send back to you. Theres a reason for the brand new websites being better to work with and faster. Their called AJAX. Maybe not the solution invented in 1947 nor the mythical Greek hero but a web develop-ment approach. AJAX isnt new technology but a variety of existing mature technologies. Its a web devel-opment way to make web pages and an abbreviation for Asynchronous JavaScript and XML feel more sensitive. It does this by exchanging small amounts ofdata with the server behind-the scenes and displays it without re-fetching the whole site at-the same time, hence the term Asynchronous. In case you are not completely clear what asynchronous means, synchronous means that processes are influenced by other processes 1 2 3 etc while asynchronous may be the ability to manage processes separately from other processes. It might seem that adding a layer to any ap-plication can make it less sensitive, but because the visitor first loads an AJAX motor responsible for both providing the program the user sees and communicating with the host on the people account the user is extremely seldom staring at an hourglass icon holding out for the serverto take action. Every user activity that normally would make work on the host visits the AJAX engine instead. Any reaction to an individual action that doesnt need a trip right back to the server the engine handles alone. It makes these requests asynchronously without affecting an users interaction with the application form if the engine needs something from the machine in order to answer. All this means AJAX is pretty just now - a little like Flash has-been. It may be very tempting to use AJAX simply because AJAX is great or my boss said to.

But when you are developing any site you must think of your customers first. What do they want this application to-do? Whatll allow it to be simpler to use? A great principle regarding whether or not to use AJAX IS: AJAX is for action not material. You should think again if youre not accessing data that changes then. The point of the request is that it makes requests to-the machine for data that has improved faster - because its happening whilst the reader is performing something else. When they click a link or button information appears straight away. You then probably should not use Ajax to get into it, if your articles or information never or seldom changes. Then youll find other issues: Page changes When a completely new page is produced theres a brief moment of re-adjustment if the information changes. Since this doesnt happen with smaller portions of the screen this becomes more evident. This could leave people wondering. Seo Search engines do not generally browse the JavaScript code required for AJAX. This may mean AJAX pages remain un-indexed unless a static page is offered. JavaScript As AJAX depends on JavaScript, which is implemented differently by different windows and sometimes even different types of the same browser the JavaScript might have to be rewritten for a number of browser s type s although background libraries are managing this, but a problem still appears if the user has switched off JavaScript support in the browser. Internet analytics Several net statistics options are based on a new page when new or updated content is shown for the user or to observe an approach including a check-out being filled.

Because Ajax adjusts this care should be taken to account for how exactly to ensure a page or even a portion of a page could be properly tracked. Clicking [http://re.vu/highqualityvacuum benistar web site] possibly provides warnings you could use with your sister. Having written anything above, Google has made a massive investment in developing AJAX web sites. All the major products and services Google has introduced such as Google Maps, Gmail, Google Groups, Google Suggest and Orkut are AJAX applications. However AJAX [and other terms such as Rich Internet Applications or RIA for tolls such as Flash] are only new terms for a technology combinations and technologies which were around for years. Given the nonsense for these terms, it is wise to not get caught up. Careful assessment of when and how to use AJAX is important. Dont forget that other programs and Flash still dont form the idea of all websites and users need functionality first. If AJAX improves the customers knowledge whether via style or rate then its worth considering watchfully..
