Discuss why do we need cache?

IT-230: Web Technologies:

Modern developers have a wide variety of techniques and technologies available to improve application performance and end-user experience. One of the most frequently used technologies is that of the HTTP cache.

HTTP caching is a universal adaptation for all web browsers. Appropriate use of these standards can benefit your application greatly, improving response times, and reducing server load. However, incorrect caching can cause users to see out-of-date content and hard to debug issues.

Question:

1. Discuss why do we need cache?
2. When HTTP caching occurs?
3. How many HTTP caching types?
4. In your opinion, could HTTP caching be harmful? and why? argue with your colleagues by posing at least one response to their post.
