TODO List

• We need more sophistication on Forwarder struct to handle h2c.

• Cache using lru crate might be inefficient in terms of the speed.

  • Consider more sophisticated architecture for cache
  • Persistent cache (if possible).
  • More secure cache file object naming
  • etc etc

• Improvement of path matcher

• More flexible option for rewriting path

• Refactoring

  • Split backend module into three parts

    • backend(s): struct containing info, defined for each served domain with multiple paths
    • upstream/upstream group: information on targeted destinations for each set of (a domain + a path)
    • load-balance: load balancing mod for a domain + path

• Unit tests

• Options to serve custom http_error page.

• Traces and metrics using opentelemetry (tracing-opentelemetry crate)

• Documentation

• Client certificate

  • support intermediate certificate. Currently, only supports client certificates directly signed by root CA.
  • Currently, we took the following approach (caveats)
    • For Http2 and 1.1, prepare rustls::ServerConfig for each domain name and hence client CA cert is set for each one.
    • For Http3, use aggregated rustls::ServerConfig for multiple domain names except for ones requiring client-auth. So, if a domain name is set with client authentication, http3 doesn't work for the domain.

• Make the session-persistance option for load-balancing sophisticated. (mostly done in v0.3.0)

  • add option for sticky cookie name
  • add option for sticky cookie duration

• etc.
