It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. It should also be able to cache and should be free of charge. Web caching at a proxy server can not only save the network bandwidth, but can also lower the access latency for the clients. Each issue features a theme, such as "Wearable Computing" or "Health Informatics," and XRDS brings exciting research trends, interviews, columns, and even career advice articles related to that theme and relevant to computer science students. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. I have a homework assignment which involves implementing a proxy cache server in Python. I also like the fact that they are based in the US and not overseas.
