* env.url_login_user signInName=admin
* env.url_login_pass password=admin
*
* // You may specify other key=value fields which may be required when submitting the form's POST action to perform the login
* env.url_login_post_fields target=http://www.example.com
*
* // Each page to test should be specified in the format of <label>=<url> where label is alphanumeric with no spaces and url is the page URL to test
* // You may specify multiple pages to time their page load by separating them with commas ,
* env.urls label_page1=http://www.example.com/page1.php,label_page2=http://www.example.com/page2.php
