I would just like to verify can we use a machine using Internet Explorer 8 for a load generator only? Will there be any issues? Controller and Vu Gen will be running on a machine using either IE6 or IE7. Thanks...
Depending upon the virtual user type you have deployed, it may not matter whether IE8 is installed or not, but for at least one type version and manufacturer of browser would be critical.
What type(s) of virtual user are you using where you have a concern about IE8?
Note: Using an HTTP virtual user it is quite easily to change the announcement string to any browser type and version you want, so you could even have a browser named "zechzeus renderer 14.7, engineering alpha, do not use on public internet,...." and have that information show up in your web server logs as the type of browser in use.
