I am using Apache using Docker on AWS. The Apache listens on port 80 and serves HTTP.
The Apache is behind an AWS ELB load balancer, which listens only on port 443 serving HTTPS.
When I request https://example.com/foo/ (with trailing slash) it works fine, my content is served.
When I request https://example.com/foo (without trailing slash) it redirects to http://example.com/foo/ - that is to say it adds the trailing slash (correctly) but redirects from HTTPS to HTTP (incorrect).
What can I do about that?
My Dockerfile is
FROM httpd:2.4 COPY . /usr/local/apache2/htdocs/
When I do the request via curl:
$ curl -v https://example.com/foo * Trying 220.127.116.11... * TCP_NODELAY set * Connected to example.com (18.104.22.168) port 443 (#0) * TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 * Server certificate: example.com * Server certificate: Amazon * Server certificate: Amazon Root CA 1 * Server certificate: Starfield Services Root Certificate Authority - G2 > GET /foo HTTP/1.1 > Host: example.com > User-Agent: curl/7.54.0 > Accept: */* > < HTTP/1.1 301 Moved Permanently < Date: Tue, 28 Nov 2017 09:17:26 GMT < Content-Type: text/html; charset=iso-8859-1 < Content-Length: 247 < Connection: keep-alive < Server: Apache/2.4.29 (Unix) < Location: http://example.com/foo/ < <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="http://example.com/foo/">here</a>.</p> </body></html> * Connection #0 to host example.com left intact
Thanks in advance.
