Just like how we say ‘customer is the king’ in marketing world, ‘cache is king’ when it comes super fast dynamic large websites. Caches have a significant role to play when it comes to having speedier access to larger websites. The effective caching basically means storing a number of web app’s resources locally without going through HTTP requests every time we access web pages. Though your initial visit to a larger website may be slow, but if it has effective caching, your subsequent visits will be much faster. It has to be taken note that the user will be able to see the pages being accessed faster only after closing the browser and then re-launching it again. But there is always a possibility of the network traffic occurring during caching. The ‘Repeat View’ is the most important aspect in the primed cache.
Why Caching is Important?
Making substantial progress in caching of the larger websites is always a hurdle since responsibility will be more for the large website owners, third party content providers and browser developers. Caching plays a vital role in addressing issues such as freeing up of size and space limitations. Caching also helps in addressing other important issues in larger websites such as bugs with less common HTTP headers followed by outdated purging logic. The most important aspect of caching relies on larger websites specifying caching headers designed for their resources.
There is a lack of awareness among users in understanding the benefits of caching. Another major cause is the resources being dynamic which means those websites cannot be cached. It is inevitable for large website owners to make their websites cacheable. However the third party content provider not following the caching standards can harm the websites embedding their content. It is necessary requirement for third party content providers to follow good caching practices for effective caching. Large websites have to specify tight norms for third parties to follow while they integrate their content and links so that effective caching is not impacted.
Misconception on Caching
Most of the users claim that many of the large website resources are missing from the cache and hence accessing them may take more time. The major reason for this problem is undoubtedly the smaller cache sizes. Larger websites will have to increase their cache sizes for including more resources being locally stored. The website owners of larger websites will have to make use of a cache-control max-age which has to be set longer. One of the common techniques employed to achieve caching is setting up a proxy server above web server which can cache pages passing through the same. Website owners need to make sure that these proxy servers are big enough to have more resources and web pages stored locally so that users can bypass the HTTP requests and access them faster.
Better Caching Practices
However, third party content providers and brochure developers need to play a significantly important role for widely adopting these better caching practices. The perfect examples of sites which have employed very effective and strong caching techniques are social networking sites like Google, Twitter and Facebook that has millions of visitors every few minutes. The browser developers also need to give focus to this aspect when they design the browsers especially for the fast processing mobility world.
For example increasing the cache size is expected to make browsing experience much more enjoyable in mobile phone devices. But it requires user activity and data correlating cache sizes. Additional focus should also be given towards personalization for providing a much faster experience while users navigate towards their favourite websites for getting the information they require. There is no doubt whatsoever in the saying ‘cache is the king’ when it comes to speedier accessing of large and dynamic websites.
