I am working in other parts of the website at this moment, but it is in my mind to start using Cloudfront or any CDN very soon. Anyway, I solved already the issue just commenting the part in the code which creates the link, inside a class whose name I can not remember now.
It is working ok and now my region is removed before the link is created.
I do not know if I did something wrong, but by the moment, at least in my case, the link works the same using:
1) https://s3-eu-west-1.amazonaws.com/s3.mysite.com/image.jpg.
Than using…
2) https://s3.mysite.com/image.jpg.
Thanks for your help on this anyway.
It is really appreciated!
