How to enable UI rendering running with proxy

[Hung dao quang]

Hi all,

 I need to customize header to bypass authentication process (consume lots of time if use UI) by setting "token: <value>", so I am going to use Proxy(integrating with BrowserMobProxy) to do

- setup proxy

- customize header for all accesses

- go to the page

- reload the page to make sure the new header is applied.

The config file:

proxy.required = true
proxy.host = localhost
proxy.port = 8081
proxy.type = MANUAL

However, the web loads with blank page

So is there a way to load actual UI on proxy mode ?
