📋 Notes

• As default, httpx checks for HTTPS probe and fall-back to HTTP only if HTTPS is not reachable.
• For printing both HTTP/HTTPS results, no-fallback flag can be used.
• Custom scheme for ports can be defined, for example -ports http:443,http:80,https:8443
• vhost, http2, pipeline, ports, csp-probe, tls-probe and path are unique flag with different probes.
• Unique flags should be used for specific use cases instead of running them as default with other flags.
• When using json flag, all the information (default probes) included in the JSON output.
