HAProxy redirecting http to https (ssl)

Question

I'm using HAProxy for load balancing and only want my site to support https. Thus, I'd like to redirect all requests on port 80 to port 443.

How would I do this?

Edit: We'd like to redirect to the same url on https, preserving query params. Thus, http://foo.com/bar would redirect to https://foo.com/bar

Answer 1

I found this to be the biggest help:

Use HAProxy 1.5 or newer, and simply add the following line to the frontend config:

redirect scheme https code 301 if !{ ssl_fc }
