Server crashes if HTTP version cant be casted from string to float
Sending a GET / HTTP/notANumber request crashes the server due to string to float conversion, this gives std::invalid_argument.
Tested on Ubuntu 20.04
Steps to reproduce:
telnet localhost 8080
GET / HTTP/notANumberBacktrace
terminate called after throwing an instance of 'std::invalid_argument'
