I was trying to implement custom domains for Azure AD B2C, so that when a user tries to login/register into my application,they should not be displayed with a URL .b2clogin.com instead should use my custom domain
While going through the MS Docs for this requirement, (Refer here) they recommend to use Azure Front Door, but they also allow to use third party WAF such as Akamai.(Refer here)
and Here the documentation (Refer here) says that Azure Front Door is required even if we bring in a third party WAF. Azure Front Door as a Component
The question is why here Azure Front Door is required ? Is there anything special Azure AD B2C Requires?
