--- Comment #7 from Stefan Eissing <ste...@eissing.org> --- Thanks for the new log. What I see on both SSE points is: 1. The client aborts the requests (RST_STREAM) after commonly 1-2 seconds, there are 2 requests that last 5 seconds and one with 18 seconds. 2. All requests produce the response headers and one chunks of body data (525 bytes on one endpoint, 447 on the other). Those are sent to the client. 3. The HTTP/2 layer does not see a second chunk from the SSE endpoints, until the 30s read timeout happens, then one more chunk is seen. 3 indicates that someone is buffering data on the proxy connection, but after 30 seconds, the buffer only contain one more chunk of data (e.g. 447 or 525 bytes, not many). The SSE sources do not seem to provide data often (is that the intention?). An initial chunk and then silence more or less. However the browser closes the open requests quite aggressively (at least it looks like this, cannot see page reloads). There is nothing blocking in the HTTP/2 layer per se that I can see. It looks as if the browser detects frequent data to come and is unhappy and the proxied endpoint does not deliver. How often should the SSE sources produce and why is the browser closing often after 1 sec after starting the request? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org
