I ran across a few interesting posts on the Application Consulting and Engineering (ACE) team’s blog that I wanted to link to here so that more folks will hopefully see them. The ACE team announced a public beta this past week for a tool created by their team named XSSDetect. This tool is a Visual Studio plug-in that does static code analysis to detect potential cross-site scripting (XSS) issues in web applications.
Here are some useful links about the XSSDetect tool and cross-site scripting:

If you are building or testing web applications, I encourage you to check out the XSSDetect tool and the information in the above links to see if it might be useful in your development and testing processes.
