Hope you are getting some good "mileage" with eValid.
Here are some other tidbits on the question you posted:
Beginning with a minimal understanding of eVManager based on the details found in our quick start webpage at:
http://www.e-valid.com/Products/Documen ... start.html You can create a simple variant like the attached .evm and .evs examples... Please create a folder called "Project" then a sub-folder called "Group", and place browser.evm inside the Project folder.
Being that the .ats when under .evm control is strictly C program language based, we will need to either consider using separate .evs file(s) which apply
the "SetUserAgent" and/or "EnvironmentVariableFile" alternative features, etc. as the selected user agent string become more complex.
For example, Chrome uses a very long string:
"Mozilla/5.0 (Windows NT 6.2; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1667.0 Safari/537.36"
Which will not be recognized in the .ats, too many control characters..., so simply -AGENT chrome is an unknown translation/assignment...
