Proxy server

How to set your browser to use a proxy:

What are Proxies, and How are They useful?
Logs are typically produced which give information on specific websites accessed by users and can also be used to monitor overall bandwidth usage. Businesses often use proxy servers to audit employee usage or to protect against data or information leaks. The only thing which we do not like about this proxy server is that it does not support secured https sites in its free plan. Although it has a crappy design, the website does well on reliability, it always gives us the right results. 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.

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: Once traffic reaches the proxy machine itself interception is commonly performed with NAT Network Address Translation.

Such setups are invisible to the client browser, but leave the proxy visible to the web server and other devices on the internet side of the proxy. There are several methods that can often be used to detect the presence of an intercepting proxy server:. A CGI web proxy accepts target URLs using a Web form in the user's browser window, processes the request, and returns the results to the user's browser. Consequently, it can be used on a device or network that does not allow "true" proxy settings to be changed.

As of April , Glype has received almost a million downloads, [20] whilst PHProxy still receives hundreds of downloads per week. Some CGI proxies were set up for purposes such as making websites more accessible to disabled people, but have since been shut down due to excessive traffic , usually caused by a third party advertising the service as a means to bypass local filtering.

Since many of these users don't care about the collateral damage they are causing, it became necessary for organizations to hide their proxies, disclosing the URLs only to those who take the trouble to contact the organization and demonstrate a genuine need. A suffix proxy allows a user to access web content by appending the name of the proxy server to the URL of the requested content e.

Suffix proxy servers are easier to use than regular proxy servers but they do not offer high levels of anonymity and their primary use is for bypassing web filters. However, this is rarely used due to more advanced web filters. Tor short for The Onion Router is a system intended to enable online anonymity.

Using Tor makes it more difficult to trace Internet activity, including "visits to Web sites, online posts, instant messages and other communication forms", back to the user. The original data are encrypted and re-encrypted multiple times, then sent through successive Tor relays, each one of which decrypts a "layer" of encryption before passing the data on to the next relay and ultimately the destination.

This reduces the possibility of the original data being unscrambled or understood in transit. The Tor client is free software , and there are no additional charges to use the network.

The I2P anonymous network 'I2P' is a proxy network aiming at online anonymity. It implements garlic routing , which is an enhancement of Tor 's onion routing.

I2P is fully distributed and works by encrypting all communications in various layers and relaying them through a network of routers run by volunteers in various locations. By keeping the source of the information hidden, I2P offers censorship resistance.

The goals of I2P are to protect users' personal freedom, privacy, and ability to conduct confidential business. Each user of I2P runs an I2P router on their computer node.

The I2P router takes care of finding other peers and building anonymizing tunnels through them. The software is free and open-source , and the network is free of charge to use. Most of the time 'proxy' refers to a layer-7 application on the OSI reference model. The difference between these two proxy technologies is the layer in which they operate, and the procedure to configuring the proxy clients and proxy servers.

In client configuration of layer-3 proxy NAT , configuring the gateway is sufficient. However, for client configuration of a layer-7 proxy, the destination of the packets that the client generates must always be the proxy server layer-7 , then the proxy server reads each packet and finds out the true destination. Because NAT operates at layer-3, it is less resource-intensive than the layer-7 proxy, but also less flexible.

As we compare these two technologies, we might encounter a terminology known as 'transparent firewall'. Transparent firewall means that the layer-3 proxy uses the layer-7 proxy advantages without the knowledge of the client. At the end of the day, a proxy server is typically used to limit the information that is accessed or to track the usage of a particular user or users. Primarily used in a business setting, proxy servers can be used in a home setting as well — particularly by parents hoping to limit the amount of offensive material their children have access to.

What are Proxies, and How are They useful? The user connects to the proxy server The user requests information or a service. This could be a connection to a specific website or a file or other resource. The proxy server applies its filtering guidelines to the request. The verified request is sent to the appropriate server. This is done by saving content made by an older request by the user. In effect, a caching proxy server keeps copies of resources that are frequently requested.
