houshunwei opened a new issue #1833: URL: https://github.com/apache/incubator-apisix/issues/1833
### Issue description I use Apisix as multi-cluster ingress as following picture shows. But I cannot go through ②，because apisix uses http to request upsterams by default。 Even I use proxy-rewrite plugins to force use https, it's not http/2 with https.  Client request has the following different flows: cross cluster request: ① --> ② --> ④ same cluster request: ③ --> ④ What should I do? Can any one give me some hint？ ### Environment * apisix version (cmd: `apisix version`): 1.4 * OS: docker， centos 7 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
