Guessing that Microsoft probably optimized OWA for its own browser I thought that I will definitely find JavaScript code that doesn’t execute that well on [...]
Keith A. Marshall, Lead Developer at Insight North America, talks about how he identifies certain transactions by injecting specific HTTP Headers “on-the-fly” using Fiddler. Performance and Scalability testing are two important components in our software development and applications deployment lifecycle.

In the last week my task was to create stable functional tests for a new eCommerce application. We picked several use cases, e.g.: clicking through the different links, logging in, searching for products and actually buying a product.

// When we get engaged with prospects that are interested in our performance management solution we walk them through a Proof of Concept. We let them install dynaTrace on their own prior to the actual POC. During the POC we ask them to exercise typical use cases on their application that show performance problems. We [...]
