Use https backend server redirect to http problem

[huang-x-h]

When we use https to access apisix, backend server use http.

Now, when we access https://example.com:9443/path/login.html, this page will be form submit and the backend server will redirect to '/path/index.html, then browser url change to http://example.com:9443/path/index.html`, not https protocol

So we add follow snippet, it's work fine.

proxy_redirect http://exmaple.com:9443/  https://exmaple.com:9443/;

The backend server is Java, we use HttpServletResponse response.sendRedirect(redirectUrl)

But i think this is not a right way, have an another way to fixed this?

@huang-x-h Did you use the redirect plugin? What does the redirect response look like (from the backend).

@huang-x-h Could you evaluate the proposal from @tzssangglass ?

Maybe is our backend code error, when we redirect the url, the response header location is http://exmaple.com:9443/path/index.html, so we use proxy_redirect to change http to https 😞

If so, what about using the serverless plugin, injecting some codes in the header_filter phase, rewriting the Location header.

yes, it's works. Thanks 👍

@huang-x-h Can you please help in understanding how to use the plugin serverless plugin for the same? I was facing the same issue when I upgraded my apisix installation to 3.15

@Padmabishek we use http server location configuration snippet, setting like this:

http server location configuration snippet: |
  proxy redirect http: //access_ip:9443 https: //access_ip:9443:
