We have a backbone frontend and the problem for us has been that because our landing page has been part of the dynamic web application each change to the landing page has required a new software release. Another problem has been that search engines generally don’t love dynamic pages.
We use HAproxy to route requests to desired backends. The desired outcome would be that usetrace.com landing page (and some sub pages) would be served by a static web server and other urls would be served by our NodeJS backend. The problem with our backbone URLs is that they use anchors, e.g. usetrace.com/#login so we cannot do routing using request path. The login view would be seen as the landing page URL by HAProxy.
A solution is to serve the dynamic app from within a subdomain, e.g. team.usetrace.com and leave the main domain for the landing page.
This can be implemented by the following HAproxy configuration.
Under the frontend block.
Create a rule for the dynamic app:
acl is_webnode hdr_dom(host) -i team
Route dynamic requests to the dynamic backend:
use_backend webnode_http_backend if is_webnode
Serve all other requests from the static backend:
default_backend static_http_backend
Then define backend configuration blocks for the two backends, e.g:
backend static_http_backend
balance source
option forwardfor # This sets X-Forwarded-For
option httpclose
option httpchk
timeout queue 100000
timeout server 100000
timeout connect 10000
server apache_http_server localhost:8089 weight 1 maxconn 1024 check inter 10000
