We seem to be an industry enamored with buzz words. Even though XmlHttpRequest has been around since the mid-90s, mainstream programmers didn’t give it a second thought until someone attached the term AJAX to it.

Chances are, at some point you've tried creating a new user account on a website and were told that the username you selected was already taken. This is especially common on very large websites with millions of members, but can happen on smaller websites with common usernames, such as people's names or popular words or phrases in the lexicon of the online community that frequents the website. If the user registration process is short and sweet, most users won't balk when they are told their desired username has already been taken - they'll just try a new one. But if the user registration process is long, involving several questions and scrolling, it can be frustrating to complete the registration process only to be told you need to return to the top of the page to try a different username.

Many websites use Ajax techniques to check whether a visitor's desired username is available as soon as they enter it (rather than waiting for them to submit the form). This article shows how to implement such a feature in an ASP.NET website using Membership and jQuery. This article includes a demo available for download that implements this behavior in an ASP.NET WebForms application that uses the CreateUserWizard control to register new users. However, the concepts in this article can be applied to ad-hoc user registration pages and ASP.NET MVC.

ASP.NET Password Strength Indicator somewhat similar to AJAX PasswordStrength extender control behavior and implemented by using jQuery and XML.

A client of ours recently contacted me with the question: We use Keynote, WebPagetest and dynaTrace AJAX – but we get different results with these tools/services. WebPagetest tells us that our page is very slow – but dynaTrace on my local machine does not. What can be the problem here? What’s the difference? I took a look at their page on my own laptop – running WinXP and IE8. I saw a small JavaScript performance hotspot but nothing major. Then it occurred to me that WebPagetest is probably using a different browser which made me notice a feature of IE that I haven’t yet explored enough.
