bonjour list, In comparison to 1.8 (and probably 1.9b5 but I can't verify that at present) the 301 redirect seems to be handled differently. Initially I thought this was an HTTP2 issue but it 's reproducible on HTTP/1.1 as well.
curl --http1.1 -4vsSLo /dev/null https://logs.example.com/ > h11_18.log or h11_19b6.log) full diff of logs are at end of the email. Interestingly this is handled differently in browsers - firefox compiles strictly with the redirect and eventually exceeds its acceptable URL length, appending the %20HTTP/1.1 each time. Chrome and forks seem to ignore it. the curl output is identical until: |< HTTP/1.1 301 Moved Permanently |< Content-length: 0 -|< Location: https://example.com/ +|< Location: https://example.com/ HTTP/1.1 where we can see under 19b6 the HTTP/1.1 sneaks in. And as we are using the -L follow option in curl we see the incorrect URL being propagated back: |* Connection #0 to host logs.example.com left intact -|* Issue another request to this URL: 'https://example.com/' +|* Issue another request to this URL: 'https://example.com/ HTTP/1.1' |* Trying 95.216.20.215... I've tried fiddling with my 301 settings in haproxy.conf to no avail. environment: FreeBSD 11.2Rp4 amd64 internet -> haproxy :443 (ipv4 or ipv6) -> h2o 2.3.0b1 backend for serving actual files. # /usr/local/etc/haproxy/haproxy.conf ... blah bind ipv4@:443 ssl alpn h2, crt ... bind ipv6@:443 ssl alpn h2, crt ... # redirect anything that doesn't match our ACLs or isn't TLS http-request redirect code 301 location https://example.com%[capture.req.uri] unless www or api or beta http-request redirect scheme https code 301 if !{ ssl_fc } I can provide full actual logs / configs off-list if needed, and it's quick to switch in versions of haproxy for validating or get pcap traces.
