Does every web request send the browser's cookies?
I'm not talking page views, but a request for an image, .js file, etc.
Update If a web page has 50 elements, that is 50 requests. Why would it send the SAME cookie(s) for each request, doesn't it cache or know it already has it?
Short answer is Yes. The below lines are from the JS documentation
Cookies were once used for general client-side storage. While this was legitimate when they were the only way to store data on the client, it is now recommended to use modern storage APIs. Cookies are sent with every request, so they can worsen performance (especially for mobile data connections).
