This seems to address issue #88. As the standard library docs suggested, the problem is related to wrapping
ResponseWriterinstances. I went through and implemented aFlushmethod for thestatusRecorderandhuma.Contexttypes. I tested this with a resource handler that was generated server side events (i.e., calledctx.Write(...)multiple times invoking.Flush()after each). Runningcurl -N ...showed that the output was, in fact, getting flushed (which was definitely not the case before these changes).I haven't tested this with an SSE client, but just running
curl -Nseems like an adequate test of the functionality for now.
