Question

*The ______ header specifies how a web browser should cache any server content it receives. a. Caching b. Cache-Control c. Cache-Level d. Cached

Answer 1

The Cache-Control header is used by web servers to define caching directives for web browsers, influencing how server content is cached and reused. The option b is correct.

Step-by-step explanation:

The Cache-Control header plays a pivotal role in instructing web browsers on how to cache server content.

This header, employed in both requests and responses, allows for the specification of caching directives, establishing rules that govern what content can be stored in the cache and the duration it remains before reuse.

For instance, by setting the Cache-Control header to "no-cache," the directive mandates that a browser must validate with the server before retrieving content from its cache.

Alternatively, employing the directive "max-age=3600" signifies that the content can be served from the cache, provided it has been stored for less than one hour.

In essence, the option b is correct, Cache-Control header serves as a crucial mechanism for optimizing web performance.
