Hello all, I just rolled out 1.9.2 compiled from the official tarball to a subset of our servers, and I'm observing some odd behavior in the logs. I'm seeing the following warning (with accompanying warnings about failed hdr rewrites in the stats page):
Proxy foo failed to add or set the response header 'bar' for request #1380. You might need to increase tune.maxrewrite I've tweaked tune.maxrewrite to 2048 with no apparent affect (it was not previously set). The further odd thing is that the header is present on the client side (seemingly every time). This is does not happen with an identical config in 1.8.x (obviously sans h2 on both ends & option http-use-htx). Any ideas regarding what I should investigate? The line emitting the warning seems to be https://github.com/haproxy/haproxy/blob/master/src/proto_http.c#L1630. I'm happy to try patches additional configuration changes if that would assist. I assume it's something slightly amiss in the HTX setup or my configuration thereof. Best, Luke — Luke Seelenbinder Stadia Maps | Founder stadiamaps.com
