Often, the environment being tested if not the same one I script in because of logistics in getting the environments ready. Without getting into the issue of poor configuration management between environments screwing up your scripts – and most LoadRunner scripters know how bad of a problem this is –  I wanted to demonstrate the use of the “Additional Attributes” run-time setting to easily change environments without changing the Read Entire Entry

In LoadRunner Vugen, there are two general modes of recording: HTML and URL.
