proxy_prefix doesn't work?

[veselov]

Hello.

I'm trying to set up oauth2_proxy with nginx. I've specified:

proxy_prefix = "/gitlab-oauth"

In the config file. However, it doesn't seem to take for ".../auth" URL:

It seems I'm stuck with using "/oauth2" root prefix?

[root@ip-10-44-6-158 oauth-proxy]# telnet localhost 4180
Trying 127.0.0.1...

Thank you for the awesome project :)

it's proxy-prefix in the config (dash, not underscore) (admittedly not matching the general convention of "dash in cmdline flag, underscore in config file")
