Syns den How to virket nyttig, men usikker på forklaringen, er ikke dette noe man finner på internett? Er vel ikke så mye som var spesifikt for oss?

Address review feedback that the page was mostly generic internet
knowledge. Cut the general HTTP/TCP tutorial material and keep what is
specific to the platform: silent idle-connection drops by
firewalls/LBs/NAT (with nav-tenant on-prem firewall details), the 30s
DNS TTL and JVM caching pitfall, pod lifecycle effects on connection
pools, and a compact timeout-type overview.

Enig — forklaringssiden var for generisk. Har kuttet den fra ~300 til ~65 linjer i 407a292, og beholdt kun det som er spesifikt for oss: stille dropping av idle connections (med on-prem brannmur-detaljene bak nav-tenant conditional), 30s DNS TTL + JVM DNS-caching, pod lifecycle-effekter på connection pools, og en kompakt timeout-oversikt. How-to-en er uendret.
