Thank you @KyleG . I have read the whole thread and I found this.
That's why, I assume the native HTTPS support in Photon is not coming any time soon.
I saw about HTTPS client by glowfish in that thread as well.
But they don't have working any example to post to private " htttps : // localhost " server which is self signed.
The closest that I can find is timeapi-test code, not fully functional and yet it provides very few comments for me to understand what is going on.
What I need is a secure way to upload to mySQL and doesn't necessarily have to be HTTPS..
But I guess I am running out of options.
