Chapter 7[ 167 ]To see how this configuration sets the headers, let's take a look at what each location
looks like in the browser. Each modern browser has a tool either built-in or available
as a plug-in that enables you to view the headers of both the request and the response.
The following series of screenshots show how Chrome displays the response headers
for these locations:
- The main page (index.html): The Expires header is set to 5 minutes later
than the Date header. The Cache-Control header has a max-age parameter
set to 300 seconds. - A CSS file: The Expires header is set to 24 hours later than the Date header.
The Cache-Control header has a max-age parameter of 86400 seconds.
