My proxy inserts XFF header by default. Some of HTTPS websites do not work if I do HTTPS interception. First I bypassed those websites from HTTPS interception and they started to work. Then I kept HTTPS interception enabled but disabled XFF interception and the websites still worked fine. So my question is what impact does XFF header have on HTTPS websites. I understand it is used to send client's original IP address but why the Websites work with XFF disabled and fail to load when XFF is enabled.
