These days web caching suffers from many problems like scalability, robustness, metadata management etc. These problems degrade the performance of the network and can also create frustrating situations for the clients. This paper discusses several web caching schemes such as Distributed Web Caching (DWC), Distributed Web Caching with Clustering (DWCC), Robust Distributed Web Caching (RDWC), Distributed Web Caching for Robustness, Low latency & Disconnection Handling (DWCRLD). Clustering improves the retrieval latency and also helps to provide load balancing in distributed environment.
