Our site shifted from http to https and based on observation, before using https, we’re able to get different cdn urls (like http://a0.twimg.com/… or http://a3.twimg.com/…) for profile images then afterwards, profile_image_url_https always return https://si0.twimg.com/… . Does it really always return si0.twimg.com?
Also, upon trying, si0 to si5 are returning the same images for a specific user. Is it safe to assume that this applies for all users’ profile_image_url_https? And is it okay to use these other cdn urls?
Hoping for your quick response and thanks a lot in advance!
