Hi folks,

Kinda new to envoy so this might be a trivial thing that I am missing. But need some help on this.

I am running envoy v1.4.0 on a Debian 8 (Jessie) system. I was playing around with it and was running envoy with the google_proxy stock config - https://github.com/envoyproxy/envoy/blob/v1.4.0/configs/google_com_proxy.json

However when I issue a curl request to google through envoy using "curl -v -x http://localhost:10000 -L www.google.com". I always get a 404 from envoy no matter what the request. A normal curl request works fine.

Here is what I see in the envoy debug logs -

Can someone help me figure what is it that could be going wrong here? Thanks in advance!

By default Envoy does not support absolute URIs. I'm not sure why you are specifying '-L'? See the 'allow_absolute_url' option here: https://envoyproxy.github.io/envoy/configuration/http_conn_man/http_conn_man.html. It might work.
