利用Redis缓存提高网页导航条性能（导航条用redis做缓存）

As an important element of website navigation, navigation bar is widely adopted on most websites, while performing an important role in website building and experience improvement. As the click demands and data updating become quickly, the response time of the navigation bars appears to be slow, which directly leads to the bad user experiences and web page prejudice. How to mntn the navigation bar response time and improve the user experience is thus the current challenge.

There are several methods to solve the problem mentioned above. In this paper, we choose to improve navigation bar performance by using Redis caching (RC), a kind of key-value database from the aspect of database.

To implement RC, first of all, we need to design a database structure which contns all the menus, link and data content of the navigation menu. Then, these menu and link data can be stored in the Redis database. Instead of getting the data from the original data source, the web application will get the data from the Redis cache.

Besides, we need to design a programmed procedure to synchronize the data between the original data source and the Redis cache. This procedure monitors the data changes and updates in the original data source, and ensures that the data in the cache is up to date.

After completing the above steps, we are going to further ensure the data security by designing a slew of other measures, such as proxy authentication and encryption, on the Redis database.

Finally, we are able to test the whole RC structure to guarantee its performance. During the test, if anything went wrong, we’ll go back and start the optimization procedure all over agn.

Given the high performance, security and scalability of RC, it is regarded as one of the most valuable methods to improve navigation bar performance, and provides great convenience for developers to build their own navigations bar.

To sum up, by using Redis caching, we can solve the slow responding time of web page navigation bar and improve the user experiences. Besides, the scalability and security of Redis is quite helpful for the building of navigation bar.
