23.1.0

January 2024 (version 23.1.0) aka Hornussen release

Codenamed as Hornussen Sport
Read the Docs: Ocelot 23.1

Focus On

Multiplexing middleware aka Request Aggregation feature

• Significant refactoring and design review of the Multiplexer
• Optimizing multiplexer performance: HttpContext is not copied when there is only one downstream route, and etc.
• Fixed the bug in the multiplexer: HttpContext.User information was not copied if there was more than one downstream request.

System routing. Content streaming when Transfer-Encoding: 'chunked'

• Correction of the bug when creating requests: The header Transfer-Encoding: chunked was present even when there was no content or the request body size was 0. These cases are now addressed.

Updates of the features: QoS, Load Balancer and Error Status Codes

• Quality of Service: Possibility of implementation of custom Polly v8.2 providers. New AddPolly extension methods.
• Load Balancer: Extension of the route key format, ensuring that the key remains unique for cases of UpstreamHost route property and ServiceName vs ServiceNamespace properties in Consul setup.
• Error Status Codes: When 413 Content Too Large, Ocelot now returns a 413 PayloadTooLargeError (Ocelot error code 41).
