Host header is being verified with port

[Ludo444]

System

• Version: 0.31
• Platform: Linux 5.13.0-52-generic in docker

Testcase

• Start geckodriver with --allow-hosts=domain.local behind proxy on different port
• Connection fails as Host header is being verified together with port

Log

Rejected request with Host header domain.local, allowed values are [domain.local:4444]

Solution

• Either do not validate port of Host header
• Or allow pass of port inside the --allow-hosts param
