Setting cookies (oAuth) to sync UI version

Hi again,

What is the preffered/best-practice work to set a cookie - in particular an oAuth cookie? I am hot-loading the UI. I was able to get the cookie working, but i had to touch the file which is wrapping the unity web-request? I suppose there is a nice way to do it.

Could you provide an example?
Thx in advance. 

best phil
