Hello I'm interested in using HAProxy as my external-facing proxy, in front of my applications. I want to implement an SSO application to handle authentication (similar to what is described here: http://dejanglozic.com/2014/10/07/sharing-micro-service-authentication-using-nginx-passport-and-redis/).
Nginx has the ngx_http_auth_request_module (http://nginx.org/en/docs/http/ngx_http_auth_request_module.html), which looks like it would work well, but I am wondering if I can do this with HAProxy, and not need Nginx as a second layer in front of my applicaitons. Can HAProxy make subrequests to determine how to handle the incoming request? Are there any resources I should check out to help with this? Thanks! -- Patrick Kaeding pkaed...@launchdarkly.com
