What is one limitation of using web caching with modern websites?

Using web caching can indeed present challenges when it comes to modern interactive websites, often referred to as Web 2.0 applications. These websites rely heavily on dynamic content, user interactions, and real-time data updates. Web caching primarily focuses on storing static content such as images, stylesheets, and static HTML files to speed up load times for users by reducing the need to fetch these resources from the server repeatedly.

In a scenario with Web 2.0 applications, which often involve personalized data and frequent updates, caching may not always provide the intended benefits. For instance, when a user interacts with a web application (like submitting a form or updating profile information), the page needs to fetch real-time data from the server. If the cache does not update accordingly, users may see outdated information or experience errors. Thus, while caching can enhance performance by serving cached content, it can also lead to issues with interactivity and real-time updates on modern websites.

Other choices present less relevant limitations regarding web caching. For instance, the claim that caching only applies to text content is incorrect, as caching can also include multimedia files and other static resources. The assertion that caching significantly reduces network speed is inaccurate, as the purpose of caching is to enhance speed by reducing data
