The access log's response writer had no Unwrap method, so http.ResponseController stopped at it and a handler's Flush or SetWriteDeadline returned http.ErrNotSupported. It now has one. With metrics on, the metrics library's std.Handler put a writer of its own in the chain with the same gap. The Metrics middleware now calls the library's Measure with a writer of ours that has Unwrap, and keeps its place in the chain. A new test sets a write deadline and flushes through the production router over a real connection, with metrics off and on, on a global route and in an admin page route group. Model: opus-5-5
