How browsers talk to servers
This is more of an outline than a tutorial. I wanted to give our web team a quick overview of what headers are and what they mean for client-server communication. Mainly, what HTTP headers mean for cookies and for other information that they see when they’re programming on web pages.
It’s unlikely I’ll ever do this tutorial again, so this document is probably more useful as a starting point for giving a tutorial, rather than as a standalone tutorial.

- Headers always look like “Some-Name: some value”.
- Manipulating headers
- The “header()” function in PHP lets you manipulate headers, and this is most commonly how we do it when we need to set headers inside of a PHP script. Browsers give us a way of manipulating the headers they’re storing for the page, in the HEAD of a web document. We use it to set the character set of our newer web pages:
