How to use external link to point to "mitm.it"

Hello, i am running a fake portal and mitmproxy at the same time. How do point the link in my fake portal to mitm.it. When uset clicks the link mitm CA portal/page opens up in their browser.

How does mitmproxy serves its CA page, i checked the web server and its not using the webserver?

Also i like to edit the CA page like html/css.

Hi,

Could you please clarify your question?
The code for mitm.it is in https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/addons/onboarding.py / https://github.com/mitmproxy/mitmproxy/tree/master/mitmproxy/addons/onboardingapp.

Hi can i have your email to show and explain further.

I want to point the mitmproxy link on a different page while mitmproxy running and with another page with the link to the mitmproxy certificate.
