Hotspot how to set up an authorization page on a hosting?

Question

Mikrotik

You need to make an authorization page (only trial) on an external hosting. As a person whose body rejects php, Google solutions brought me only a total misunderstanding, so the question is:

How to make the hotspot authorized by clicking on an external page? There is a page, and the redirect to it works.

Is it possible to make the page open immediately, i.e. so that the router does not load the page from memory at all, and already makes a redirect from it, but immediately opens the page on the hosting
