Having authenticated with WebAuth using an SSO username and password, the PHP script is executed. As you can see, the PHP script is passed a parameter which is the URL of a login page of a Rails application.

As a web programming language, one of PHP’s strengths traditionally has been to make it easy to write scripts that access databases so that you can create dynamic web pages that incorporate database content. This is important when you want to provide visitors with information that is always up-to-date, without hand tweaking a lot of static HTML pages. However, although PHP is easy to use, it includes no general-purpose database access interface. Instead it has a number of specialized ones that take the form of separate sets of functions for each database system. There is one set for MySQL, another for InterBase, and another for PostgreSQL—and others as well.

Online chat solutions have been very popular long before AJAX was born. There are numerous reasons for this popularity, and you’re probably familiar with them if you’ve ever used an Internet Relay Chat (IRC) client, or an Instant Messenger (IM) program, or a Java chat applet. AJAX has pushed online chat solutions forward by making it easy to implement features that are causing trouble or are harder to implement with other technologies. First of all, an AJAX chat application inherits all the typical AJAX benefits, such as integration with existing browser features, and (if written well) cross-platform compatibility.

Web application technologies like PHP, CGI, Javascript, and Ajax have made it much easier for people to construct and deploy services on the Internet. Unfortunately, this has opened a wide avenue for new attacks since it is as easy to unintentionally introduce new vulnerabilities into web applications as it is to intentionally introduce new functionality. Consequently, web applications have increasingly been the focus of attackers.
