****UPDATED****See Floris Kraak's comments below, he has a much more elegant solution.......****UPDATED****It is common practice for testers to use local HOSTS files to direct traffic from Load Generators to the application under test. If possible the URLs should be parameterised, this allows the URLs to be changed quickly, for example when switching between development and test environments. Some web servers, however, host multiple websites and direct traffic to the appropriate site using host headers.
This is a follow-up to a blog article that I wrote after a recent engagement at a client site where I was involved in planning a migration of performance tests from LoadRunner to Performance Center. The original article had some tips about the use of test data. This article expands on that.During my time on site, I spent some time reviewing my client's scripts.
