Cache web proxies
List with hand glass In practice, cache proxies are often used. this sort of proxy stores a replica of the online pages you've got visited, which suggests that these pages are often accessed more quickly and randomly. If a particular page is named up, the proxy only looks within the local cache to ascertain whether this page has already been saved. If this is often the case, this data is shipped on to the user. If the page has not yet been saved, the info is retrieved from the target server then forwarded to the user. a replica of the info is stored within the local cache for future requests.

The cache periodically clears data, counting on how big and the way old it's and the way often it's queried. Two simple cache algorithms are Least Recently Used (LRU) and Least Frequently Used (LFU). LRU deletes data that has not been queried for an extended time; LFU deletes data that's least frequently requested.

Filtering web proxies
Web proxies also can filter the content of internet sites . Some sorts of internet blockades and online censorship, e.g. State censorship in China works through web proxies that decide which parts of the network are accessible and which aren't .

Web proxies customize websites for a selected target or audience. for instance , you're often redirected to the mobile version of an internet site once you use your smartphone. Internet providers also use this sort of proxy against viruses and other malicious content. A filter proxy therefore blocks certain content. This limits the liberty of the web , but contributes to security.

Reverse proxies
A reverse proxy is that the opposite: rather than protecting the info of the surfing user, the info of the online server is protected behind a firewall. this will block access to certain pages on the server. Customers of a bank can e.g. never just check out foreign bank accounts. Reverse proxies also can be wont to cache static pages and stop page overload.

CGI proxies (the 'Pirate Bay' proxy)
A special proxy type is that the CGI proxy, where the user logs in via a special website so as to realize access to a server via the proxy. These websites / proxies mostly work using PHP or CGI. With CGI proxies, blockages in class or company networks, also as state blocks, are often avoided for sites like The Pirate Bay. Since they also obscure the user's IP address, they're sometimes used for a touch extra anonymity.

Transparent proxies
So far, we've differentiated between proxies consistent with how they work, but they will even be divided consistent with the extent to which they protect the user's privacy on the web . A transparent proxy server doesn't hide the user's IP address. They identify themselves on websites as proxy servers and expire the first IP address of the request. These servers aren't used for anonymization, but as cache proxies.

Anonymous proxies
This type of proxy server identifies itself as a proxy for web servers, but doesn't expire the particular IP address of the user. Anonymous proxies offer their users a moderate level of anonymity. An anonymous proxy connection therefore doesn't give access to Netflix, since Netflix recognizes that it's a proxy and blocks access for the foremost part.

Highly anonymous proxies
This type of proxy doesn't identify itself as a proxy server and doesn't expire the user's IP address. it's therefore completely invisible for websites that this is often a proxy connection, while 'normal' anonymous proxies can easily be recognized intrinsically . during this respect, this sort of proxy is best like a VPN, but the safety of a VPN connection is additionally lacking here.

Advantages of proxies
The use of proxies has several advantages. Some proxies affect your connection speed and security online. Some proxies offer various extra functions, e.g. blocking certain websites or bypassing certain blocks. and eventually , a proxy hides (partially) your IP address. Read more about these benefits below.

Cache proxies store copies of the pages you've got visited. this will improve your connection speed: If you call up the page a second time, it doesn't got to be reloaded, but the saved copy is displayed. This also reduces the bandwidth required when surfing.

Proxy servers also can be wont to detect and stop malicious code on websites. this enables proxies to supply a further layer of protection between you and potential malware, reducing the danger of infection.
