I have a video website which I recently changed from http to https.
And I have also made an htaccess entry to automatically 301 redirect all http urls to https.
The old video embed code links given to external customer sites are like :
Some customer websites also changed to http to https. In those https websites the above link with http protocol won't work because of mixed content. I have no control over the customer sites to change those urls to https. I checked whether any automatic redirection exists for this problem. But cannot find anyone. So every client website should have to manually change the embed code url to https.
