Oh ok.
then I tried to save a actual content(image file) in session but I can’t do this
(Plug.Conn.CookieOverflowError) cookie named “_myapp_key” exceeds maximum size of 4096 bytes
I think this is because image file is too book to save in session data.
So what is better solution?
Why I am trying to do this is I want an user check the image before save to Amazon s3.
