Question about routing logic

[Fweddi]

I'm interested in the logic of the following lines. Why would you change the url, rather than keeping the same endpoint and serving up the file?

if (req.url === "/") {
      req.url = "/public/indexProtected.html";
    }

Router.js, lines 9-11

This way we don't need to have a separate handlers just for our homes. They will be served as other public files. It is acting as if '/' were a 'link' to actual files. We have no other reasons to create separate handlers for our '/'. Also depending on wheter you are logged in or not it links to different routes. Not sure if it explain anything... Sorry.

When I was working with Lungs team they were doing this as well. I thought editing the variable passed in was wrong as not pure function and then implemented it differently.

It seems like the groups learnt to do it this way form a workshop or something and perhaps should be corrected (if it's a problem)
