HTTP Request with bad HTTP version in header crashes server
The HTTP server crashes if it receives a header with HTTP version as string or large number.
OS: Ubuntu 20.04
Project version: 260755ec
Error: terminate called after throwing an instance of 'std::invalid_argument' what(): stof
Steps to reproduce:
Clone the project from the above commit
Follow README.md to build and run
Use telnet or similar to send a request, f.ex.:
telnet localhost 8080
GET / HTTP/notanumber #press enter twiceStacktrace:
terminate called after throwing an instance of 'std::invalid_argument'
what(): stof
