Release Notes

Added

  • Add per-upstream logging controls for pass-through-only reverse proxy usage.
  • Support Base64URL/Fernet-style long payload folding in request and response bodies. Fixed
  • Avoid marking client-canceled streaming responses as proxy errors.
  • Filter upstream CORS response headers so PrismCat keeps CORS policy control.
  • Preserve original request body details when request override fails.

Installer type: portable
