How to configure site_url so that the protocol is specified only through a double slash //?

Question

MODX

Good day, developers! MODX has a template variable http://askmeplz.com/, which displays an address with a protocol: either https://site.ru or site.ru. Tell me how and where to set up the output so that the address is displayed through two slashes: //site.ru.

Answer 1

//askmeplz.com
And it's better to put it in a new parameter in the config.

Answer 2

Hello, you can use an I / O filter, in your case it will be like this:
