Add configurable upstream connection limits#235
Merged
Conversation
Add new --upstream.max-idle-conns and --upstream.max-conns options to configure the HTTP transport connection pool settings. - max-idle-conns: max idle connections total (default: 100) - max-conns: max connections per upstream host, 0=unlimited (default: 0) This allows users to limit concurrent connections to backend servers, preventing connection exhaustion when upstreams have limited capacity. Related to #159
Use require.Eventually to wait for server readiness instead of fixed sleep, preventing connection refused errors on CI.
