Thank you @PitaJ . I'm unsure which file in the NodeBB repo to adjust if I want to add a cookie to the response though. I'm fairly new to express rendered templates. Would you recommend me working in the render.js file?

I am using a plugin that allows users to auth using my own oAuth system. I figured out that I can not set an HttpOnly cookie across domains from the response header, so I am trying to figure out if there is a hook within NodeBB that will allow me to set a cookie. My oAuth system resides on a different domain. I could duplicate it on the current domain, but would really like to avoid it. Can anyone offer any help?
