How to localize part of the traffic for a web browser?

Question

Computer networks

Good afternoon, dear web development gurus
, tell me, please, are there any options for taking some of the files that the web browser requests from local storage?
you need something like this: if the link to the file matches a certain mask, then this link is replaced by a local
one; if the file does not fit the mask, then it is requested on the Internet, for example,
if it is a link localhost/reports/sales01.pdf is given
otherwise this file is already requested on the internet, for example www.mycompany.com/img/logo.jpg

Answer 1

what you describe - in a strange way it looks like a proxy;)
As I understand it, you need a managed one? Well, something like that. We host the site on our nginx, edit the dns so that clients point to you, well, we teach nginha to go to the site by default for content, and for some - to your storage ...
Well, or you can try to screw all sorts of squidguard and the like... .
