Replicator: HTTP/1.0 404 Not Found with Openshift and Port 443

[florianfiby]

When using SyncGateway on Openshift with Route on Standard Port (443) there is 404 Not Found while starting die Replicator. Problem is the port on the Header "Host: xxx:443".

Sending request to [https:/xxxx:443/yyy/_blipsync
                GET /yyy/_blipsync HTTP/1.1
                Host: myhost:443
                Cookie: SyncGatewaySession=***

                Sec-WebSocket-Protocol: BLIP_3+CBMobile_3,BLIP_3+CBMobile_2
Got response:
                HTTP/1.0 404 Not Found
                Connection: close
                Content-Length: 9

Same request is working on Postman.

I think I've found the issue in Networking/HTTP/HTTPLogic.cc: "Host: " << string(slice(_address.hostname)) << ':' << _address.port << "\r\n";

I've found this issue using flutter https://github.com/cbl-dart/cbl-dart/tree/main/packages/cbl_ffi

What does Postman have this header as?

[florianfiby]

I've sent exactly the same request, but changed HOST to "Host: myhost" as the service is running on 443 standard port. I think the openshift reverse proxy is not able to route the request when sending the Host header with a default port included.

I was able to build couchbase-lite-C and modified Networking/HTTP/HTTPLogic.cc for testing. Now I was able to connect the syncgateway

Does this happen in plain installs as well, or just this particular setup?

[florianfiby]

Well I cant say that, cause it's a client side setup and I don't know the history. I think openshift uses haproxy with templates and the routing is not working with a port included in the http host header.

But as far, as I found informations about http rfc the port information inside Host Header is optional, and every modern browser is just sending it on non standard ports.

[borrrden]

Seems like a change that would be easy enough to make, as long as Sync Gateway is not going to care either way.

Migrated to CBL-3651

[florianfiby]

Do you know, when this change will be solved?

[borrrden]

If you mean merged, probably sometime soon. If you mean released, that is TBD.
