AJAX is a cross-platform technique that can be use on different operating system and web application based on JavaScript and DOM. It is a powerful approach of web application technique using client-side scripting to exchange data with the web server. This means that with AJAX, web pages increases interactivity and faster responsiveness of user interface by having an independent communication with the server. Gone are the traditional ways of web browsing whereby a new page communicates with each user's request. This creates dynamic web application user interface that renders effective usability of every desktop applications. AJAX primary purpose is to increase the web page's interactivity, speed, functionality, and usability.

Ajax, by definition, is not technology. In fact, it is an application of several technologies. Ajax incorporates several existing web application like XHTML and CSS for standard-based presentation; the Document Object Model for dynamic display and interaction; XML and XSLT for data interchange between the server and the client; the XMLHttpRequest to exchange asynchronous data with the web server; and the use of JavaScript as the core code for running AJAX application.

To understand AJAX, first we must know how the traditional web application works. The classic web interface trigger an HTTP request back to web server. The server then process and retrieve data before returning an HTML page to the users. This process as a model for hypertext medium makes technical sense. But as web application evolves this process does not make the user interface more interactive and practical.

AJAX, on the other hand, eliminates this problem. AJAX speed up the loading of any web application with the use of intermediary between the user and the server called AJAX engine. This adding of another layer application of eliminates the start-stop-start-stop nature on the web. The browser loads an AJAX engine at the start of session.

The AJAX engine allows the user interface and the application to interchange data asynchronously-independent of the communication to the server. So the interaction between the user and the web never slows down, no point of waiting for the server to do something.

AJAX is a powerful technique that grows exceedingly as web application. That is, AJAX is now part of the guiding principle as web 2.0 flourishes and become a practical reality. With the power of AJAX, many of the business and marketing web site are integrated with AJAX application server platform now. Most of the major products of Google such as Gmail, Google Maps, and Google Suggest are employing AJAX application. Other web services like the photo-sharing application Flickr, Amazon's A9.com, and the new Yahoo! maps depends on AJAX. The application of AJAX comes from simple function to the most complex program like Google Maps.

Just what is a 301 Redirect?

There seems to be a lot of confusion as to what to do when you move, delete, or want to redirect incoming web traffic from an 'old' web page to a 'new' web page. A 301 redirect is the most efficient method for web page redirection from an old web page to a new web page location. There is also some confusion as to how to handle the complete move or redirection from one web domain to another web domain. According to Google, "If you need to change the URL of a page as it is shown in search engine results, we recommended that you use a server-side 301 redirect instead."

How to Set Up a 301 Redirect

Depending on your web environment, there are several methods to set up a 301 redirect. A 301 redirect is not that hard to implement and it should preserve your search engine rankings for that particular page or web domain.

.htaccess 301 Redirection

The .htaccess file needs to be placed in the root directory of your old website. In this example, we are redirecting incoming web traffic from an old domain to a new domain.

Options +FollowSymLinks

RewriteEngine on

RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

The .htaccess file is the most common method used for 301 web site redirection.

PHP 301 Redirection

You would place this code in a file at the old location.

Header( "HTTP/1.1 301 Moved Permanently" );

Header( "Location: http://www.new_location.com" );?>

IIS 301 Redirection

• In Internet Services Manager, you need to right click on the file or folder you wish to redirect
• Select the radio button titled "a redirection to a URL".
• Enter the redirection web page
• Check "The exact URL entered above" and the "A permanent redirection for this resource"
• Click on 'Apply'

That is all there is to it.

There are other methods in addition to set up a 301 redirection which include coding for ASP, ASP.NET, Java, CGI, Cold Fusion and Ruby on Rails. The above are the most common that I've encountered. When set up correctly, a 301 redirect will preserve your search engine rankings when it is necessary to move files around or switch, or consolidate, domain names.

Web design for a competitive business isn't easy, especially when you add e-commerce (the buzzword for buying and selling online) to the mix. Thankfully, many service providers have basic web hosting templates available to their customers at little to no cost depending on your package. More complex templates can be quite expensive. Companies that provide hosting with templates make setting up and maintaining an e-commerce website possible for people without the expertise to do it themselves and without the money to hire a professional to design their site from the ground up.

When purchased separately from your web hosting package, a template can run anywhere from $20 for a basic, simple web template and well into the hundreds of dollars for a more complex, custom design. For the majority of small business owners, basic templates designed for businesses are usually a safe bet.

An e-commerce template may include basic pages, search and navigation tools such as a virtual shopping cart, but it will be up to you to find your own online payment processing - most often through a third party provider such as PayPal. A web search for "online payment processing" will provide you with several options.
