How to connect svg sprite correctly?

Question

HTML

Hello, please tell me how to correctly connect the svg sprite. Insert it into html somewhere at the beginning of the page and then put everything in its place with links (but it will turn out to be a big html). Or connect the sprite with an external file, BUT here I have doubts that every time using use xlink I will have requests to this file. Or if you connect it through an object, there will be only one request to connect it?

Answer 1

BUT here I have doubts that every time using use xlink I will have requests for this file.

There will be one request, then the file will get into the browser cache.
