  4. 4. Transparent ProxyTransparent ProxyThis type of proxy server identifies itself as aproxy server and also makes the original IPaddress available through the http headers.These are generally used for their ability tocache websites and do not effectivelyprovide any anonymity to those who usethem. However, the use of a transparentproxy will get you around simple IP bans.They are transparent in the terms that yourIP address is exposed, not transparent inthe terms that you do not know that you areusing it
  5. 5. Anonymous ProxyAnonymous ProxyThis type of proxy server indentifies itself as aproxy server, but does not make the originalIP address available. This type of proxyserver is detectable, but providesreasonable anonymity for most users.
  6. 6. Distorting ProxyDistorting ProxyThis type of proxy server identifies itself as aproxy server, but make an incorrect originalIP address available through the httpheaders.
  7. 7. High Anonymity ProxyHigh Anonymity ProxyThis type of proxy server does not identifyitself as a proxy server and does not makeavailable the original IP address.
  8. 8. Web proxiesWeb proxiesA common proxy application is a caching Webproxy. This provides a nearby cache of Webpages and files available on remote Webservers, allowing local network clients toaccess them more quickly or reliably.
  9. 9. When it receives a request for a Webresource (specified by a URL), a cachingproxy looks for the resulting URL in its localcache. If found, it returns the documentimmediately. Otherwise it fetches it from theremote server, returns it to the requesterand saves a copy in the cache. The cacheusually uses an expiry algorithm to removedocuments from the cache, according totheir age, size, and access history. Twosimple cache algorithms are Least RecentlyUsed (LRU) and Least Frequently Used
  10. 10. Web proxies can also filter the content of Webpages served. Some censorwareapplications - which attempt to blockoffensive Web content - are implemented asWeb proxies. Other web proxies reformatweb pages for a specific purpose oraudience; for example, Skweezer reformatsweb pages for cell phones and PDAs.Network operators can also deploy proxiesto intercept computer viruses and otherhostile content served from remote Webpages.
