Proxy bouncing can be used to maintain privacy. For this reason, passwords to online services such as webmail and banking should always be exchanged over a cryptographically secured connection, such as SSL. This only works with DHCPv4. The I2P anonymous network 'I2P' is a proxy network aiming at online anonymity. For Wikipedia's policy on editing from open proxies, please see Wikipedia: Always working and fast. Clearing cookies, and possibly the cache, would solve this problem.

Caching proxies were the first kind of proxy server. Web proxies are commonly used to cache web pages from a web server. A proxy that is designed to mitigate specific link related issues or degradations is a Performance Enhancing Proxy PEPs. These typically are used to improve TCP performance in the presence of high round-trip times or high packet loss such as wireless or mobile phone networks ; or highly asymmetric links featuring very different upload and download rates.

Another important use of the proxy server is to reduce the hardware cost. An organization may have many systems on the same network or under control of a single server, prohibiting the possibility of an individual connection to the Internet for each system.

In such a case, the individual systems can be connected to one proxy server, and the proxy server connected to the main server. A translation proxy is a proxy server that is used to localize a website experience for different markets. Traffic from global audiences is routed through the translation proxy to the source website.

As visitors browse the proxied site, requests go back to the source site where pages are rendered. Original language content in the response is replaced by translated content as it passes back through the proxy. The translations used in a translation proxy can be either machine translation, human translation, or a combination of machine and human translation. Different translation proxy implementations have different capabilities.

Some allow further customization of the source site for local audiences such as excluding source content or substituting source content with original local content.

An anonymous proxy server sometimes called a web proxy generally attempts to anonymize web surfing. There are different varieties of anonymizers. The destination server the server that ultimately satisfies the web request receives requests from the anonymizing proxy server, and thus does not receive information about the end user's address. The requests are not anonymous to the anonymizing proxy server, however, and so a degree of trust is present between the proxy server and the user.

Many proxy servers are funded through a continued advertising link to the user. Some proxy servers implement a logon requirement. In large organizations, authorized users must log on to gain access to the web. The organization can thereby track usage to individuals. Other anonymizing proxy servers, known as elite or high-anonymity proxies, make it appear that the proxy server is the client.

A website could still suspect a proxy is being used if the client sends packets which include a cookie from a previous visit that did not use the high-anonymity proxy server. Clearing cookies, and possibly the cache, would solve this problem. Advertisers use proxy servers for validating, checking and quality assurance of geotargeted ads.

A geotargeting ad server checks the request source IP address and uses a geo-IP database to determine the geographic source of requests. A proxy can keep the internal network structure of a company secret by using network address translation , which can help the security of the internal network. Proxies can also be combined with firewalls. An incorrectly configured proxy can provide access to a network otherwise isolated from the Internet.

Proxies allow web sites to make web requests to externally hosted resources e. Proxies also allow the browser to make web requests to externally hosted content on behalf of a website when cross-domain restrictions in place to protect websites from the likes of data theft prohibit the browser from directly accessing the outside domains.

Not to be confused with secondary market , secondary market brokers use web proxy servers to buy large stocks of limited products such as limited sneakers [12] or tickets. Web proxies forward HTTP requests. This request is sent to the proxy server, the proxy makes the request specified and returns the response. Also known as an intercepting proxy , inline proxy , or forced proxy , a transparent proxy intercepts normal communication at the network layer without requiring any special client configuration.

Clients need not be aware of the existence of the proxy. A transparent proxy is normally located between the client and the Internet, with the proxy performing some of the functions of a gateway or router. In a security flaw in the way that transparent proxies operate was published by Robert Auger, [15] and the Computer Emergency Response Team issued an advisory listing dozens of affected transparent and intercepting proxy servers.

Intercepting proxies are commonly used in businesses to enforce acceptable use policy, and to ease administrative overheads, since no client browser configuration is required. This second reason however is mitigated by features such as Active Directory group policy, or DHCP and automatic proxy detection. Intercepting proxies are also commonly used by ISPs in some countries to save upstream bandwidth and improve customer response times by caching.

This is more common in countries where bandwidth is more limited e. Firstly the original destination IP and port must somehow be communicated to the proxy.

This is not always possible e. There is a class of cross site attacks that depend on certain behaviour of intercepting proxies that do not check or have access to information about the original intercepted destination. This problem may be resolved by using an integrated packet-level and application level appliance or software which is then able to communicate this information between the packet handler and the proxy.

Intercepting also creates problems for HTTP authentication, especially connection-oriented authentication such as NTLM , as the client browser believes it is talking to a server rather than a proxy. This can cause problems where an intercepting proxy requires authentication, then the user connects to a site which also requires authentication.

Finally intercepting connections can cause problems for HTTP caches, as some requests and responses become uncacheable by a shared cache. This proprietary protocol resides on the router and is configured from the cache, allowing the cache to determine what ports and traffic is sent to it via transparent redirection from the router.

This redirection can occur in one of two ways: MySpace, FaceBook, Wikipedia or any other website blocked at your work, home, school or country? They won't be restricted using US Web Proxy - free web proxy. Each website address you visit will have an encoded URL provided by US Web Proxy, which will expire after you leave the browsing session.

It making your visit history virtually untraceable. Hackers could spy on your internet connection and see which websites you are visiting and may be able to intercept data and collect your credit card information.
