That leads to the question of Does VSTS support IE8? Will it really open the 6 connections per host?
Well luckly the answer to both questions are YES ...
- VSTS 2008 SP1 has the IE8 Option in the Browser Mix
- By testing IE8 in the load test, it worked :)
It opened 6 concurrent connections per host.
The test was created by having a load test with one web test in it, and one concurrent user, once ran against IE7 and another run against IE8.
