It tells the cache which parts of a client request message to use when looking for possible cache entries. Without it only the URL is used and that prevents HTTP features like compressed responses, per-user customization of page contents, login vs non-login views of pages, and user language translations from working properly. Technical details at <https://tools.ietf.org/html/rfc7231#section-7.1.4> PS. since you seem not to already know HTTP the wordpress plugins might be the best way to start from. See what they do to HTTP messages vs the HTTP documentation (RFCs 7230 to 7235), with the redbot tool as a way to get a quick explanation about caching related features they enable.
