How to create a unique pageview counter using C# and Asp.Net Core?

Question

ASP.NET

I need the counter to count only unique views or after some time.
Where can I read about this or maybe someone has an example

Answer 1

A user has entered, check for the presence of an installed cookie with the name you need, if it is not there, then the user is new, take it into account and set a cookie with a life of 3 months. (for example)

Answer 2

Like Peter says or something like that or nothing.
HTTP
HTTP_header_field Write in
more detail what is the uniqueness criterion in your case.
One device, one browser, one user or whatever.
Need statistics for all pages, or for one.
You can use JS or not.
JS can get a lot of information.
Google - how google analytics work.
C# by itself will not be able to do anything in your case, except for cookies.
