                Web cache is a technology that temporarily stores frequently accessed web resources, such as images and scripts, locally on a user's device or on a proxy server. When a user requests a web page, the browser or proxy server checks if the content is available in the cache. If present, the content is delivered faster, reducing page load times and conserving network bandwidth.<\/p>"},{"question":"Who first introduced the concept of Web cache?","answer":"

                The concept of Web cache was introduced by Roy T. Fielding in 1994 in his dissertation titled \"HTTP - The Protocol of the Web.\" He laid the foundation for implementing web cache in modern browsers and proxy servers.<\/p>"},{"question":"What are the key benefits of using Web cache?","answer":"

                The key benefits of using Web cache include reduced latency, bandwidth savings, offline accessibility, and reduced server load. These features enhance web page loading speed and overall user experience.<\/p>"},{"question":"How does Web cache work internally?","answer":"

                Web cache consists of two main components: the cache database and the cache replacement policy. The cache database stores cached web resources, organized as a key-value store. The cache replacement policy determines which resources are evicted from the cache to make room for new content.<\/p>"},{"question":"What types of Web cache exist?","answer":"

                There are several types of Web cache, including:<\/p>
