## Motivation and Context PR modelcontextprotocol#290 documented that `StreamableHTTPTransport` requires a single-process server. However, when running multiple server instances behind a load balancer, requests for the same session must be routed to the same instance since session state is stored in memory. This adds a note about using sticky sessions (session affinity) based on the `Mcp-Session-Id` header. ## How Has This Been Tested? Documentation-only change. ## Breaking Changes None.
