Below you can find the slides to my presentation "Web-sovellusten liikenteen debuggaus ja testaus" that I gave at TechDays 2010. They are only available in Finnish. You can also optionally download the demo web application that was used to demonstrate different scenarios with Fiddler. The ZIP archive contains also the SQL script and some simple setup instructions (the latter only in Finnish as well).
