Pipeline Permintaan (Request Pipeline)

Modul pipeline mendefinisikan urutan eksekusi middleware dan kebijakan tata kelola HTTP khusus. Modul ini mengevaluasi request terhadap ambang batas load shedding, standar preflight CORS, propagasi trace context, dan isolasi keamanan. Pipeline beroperasi sebagai model lapisan dua arah deterministik yang membungkus penerus upstream.

Catatan (Notes)

RequestPipeline

Mengeksekusi kebijakan terdaftar dalam urutan fase ketat: pra-perutean, autentikasi, transformasi, dan eksekusi upstream.

HttpProblems

Menstandarkan payload kesalahan RFC 7807 dan RFC 9457 di semua kebijakan yang memotong alur request.

LoadShedPolicy

Memantau latensi P95 dan menolak kelebihan trafik dengan status 503 Problem Details saat kapasitas sistem habis.
