Clear Browser Cache: How to accomplish it

One of the best methods to restore space to your computer or phone or to fix a problem that may have been driven by a temporary file screwing up the works is also one of the easiest: to clear the browser cache.

Unfortunately, however, you may be unaware of otherwise invisible feature unless you’ve been introduced sometime in the past to clear your cache.

A Web cache is a strategy for optimizing the World Wide Web. It is executed both client-side and server-side. Caching images and other files can result in a minor overall delay when browsing the Web.

Forward and Reverse cache

A forward cache is a cache beyond the web server’s network, e.g., in the client’s web browser, an ISP, or a corporate network. A network-aware forward cache only caches laboriously accessed items. For example, a proxy server between the client and web server can assess HTTP headers and select whether to store web content.

A reverse cache models in front of one or more web servers, revving requests from the Internet and reducing peak server load. A content delivery network (CDN) usually retains copies of web content at various points throughout a network.

HTTP options

The Hypertext Transfer Protocol (HTTP) defines three primary mechanisms for controlling caches: freshness, validation, and invalidation. It is specified in the header of HTTP response messages from the server.

Freshness authorizes a response to be used without re-checking it on the origin server. Instead, both the server and the client can control it. For instance, the Expires response header delivers a date when the record becomes stale, and the Cache-Control: max-age directive conveys to the cache how many seconds the reaction is fresh.

Validation can check whether a cached response is still good after it becomes stale. For example, if the answer has a Last-Modified header, a cache can create a conditional request using the If-Modified-Since header to notice if it has changed. The ETag (entity tag) mechanism lets both solid and weak validation.

Invalidation is usually a side impact of another appeal that passes through the cache. For instance, if a URL associated with a cached response afterward gets a POST, PUT or DELETE submission, the cached response will be invalidated. Many CDNs and network equipment manufacturers have replaced this standard HTTP cache control with dynamic caching.
