User Agent String

Web browsers send a user agent string to a website’s server to indicate:

• What browser is in use (e.g. StayLinked)
• The version of the browser in use (e.g Staylinked/1.0 < build number > / < device ID >)
• The operating system (e.g. Android 10)
• Sometimes device details (e.g. Tablet)

The 'User agent string (optional)' input field enables injection of additional information into the string. Some injection examples might add OS security patch level, MDM tags, or site codes.
