Syntax: full user-agent string
Set the User-Agent (browser type) to report to web servers. Normally Webinator reports itself as "Mozilla/4.0 (compatible; T-H-U-N-D-E-R-S-T-O-N-E)". Modify this setting to report as a different user agent. If you want to emulate a particular browser, you can access your site with that browser, then check the site's transfer log to see what user agent string was logged (typically the last double-quoted entry on the line).
