An Update-Risk Based Approach to TTL Estimation in Web Caching

  title={An Update-Risk Based Approach to TTL Estimation in Web Caching},
  author={Jeong-Joon Lee and Kyu-Young Whang and Byung Suk Lee and Ji-Woong Chang},
Web caching is an important technique for accelerating web applications and reducing the load on the web server and the network through local cache accesses. As in the traditional data caching, web caching poses the wellrecognized problem of maintaining cache consistency. Web caching, however, has the leeway of delaying the refreshment of caches when the web server updates the original data, i.e., web caching tries to get better performance allowing tolerable inconsistency. This weak… CONTINUE READING
