Problem with casting in server_http.hpp file
When you give the server a GET / HTTP/notANumber it crashes and sends a invalid argument. This happens because of string to float conversion in the server_http.hpp file.
OS: Ubuntu 18.04
To recreate:
telnet localhost 8080
GET / HTTP/someword
terminate called after throwing an instance of 'std::invalid_argument'
what(): stof
Program received signal SIGABRT, Aborted.
