I am trying to do a setup for custom URL for salesforce community. I created a CName record and mapped it to proper site. Its working fine for all HTTP URL. But after a user get logged-in to the community portal , its URL is changing from HTTP to HTTPS and from that point the custom URL is not working. And I can see the force.com in my community URL.
Please suggest how I can achieve the custom URL for HTTPS URL in community.
