Looking for some Google updates Right? YES, I am here to give you a new update of Google to you guys. Google has tendency to update its algorithm time to time. This time, Google is providing update on cache-control and role of your website header in it.
Google says, the Cache-Control general-header do not impacts GoogleBot and how it crawls your web pages. This is a big update in my point of view. As you already know, the cache-control general-header "field is used to specify directives for caching mechanisms in both requests and responses," says MDN docs.
“Caching directives are unidirectional” means if there is a directive given in a particular request it doesn’t mean that the same directive will come with its response. So using this header in a webpage should not impact how GoogleBot picks up content on the page.
