For many years I've observed requests for page license.php on my webservers, from various IPs and with various User Agent Strings:
A couple of days ago (September 12th), I got 3 requests with User Agent String "$ua.tools.random()" (IP 18.104.22.168).
This must be a configuration error: it looks like an expression to select a random User Agent String.
Please post a comment is you recognize this type of expression ($ua.tools.random()), and know which tool or programming language this is.
