HAProxy path_beg not redirecting

问题

I'm testing a simple haproxy rule to make http://localhost/haproxy-dconv take me to http://cbonte.github.io/haproxy-dconv but it isn't working. 404 response seems to be from the site but the path isn't resolving.

frontend HTTP
  mode http
  bind *:80

  acl url_dconv path_beg /haproxy-dconv
  use_backend dconv-backend if url_dconv

backend dconv-backend
  mode http
  server dconv cbonte.github.io

Try this -

frontend HTTP
    mode http
    bind *:80
    use_backend dconv-backend if { path_beg /haproxy-dconv/ }

backend dconv-backend
    mode http
    server dconv cbonte.github.io

回答2:

That is because the Host header that is being sent is localhost, instead of cbonte.github.io. Add this to your backend:

http-request set-header Host cbonte.github.io

Also note that without the ending slash, you will get a 301, so make sure you send http://localhost/cbonte-dconv/ and fix your ACL.
