A proxy server is a machine that sits between the proxy users and the servers that they need access to. When a proxy user requests a certain remote resource using a URL, the proxy server receives this request and fetches the resource to fulfill the client’s request. This process enables the proxy server to store the requested content in a cache. Any new request that asks for information already in the cache no longer needs to be serviced by fetching it from the remote server. Instead, the new request is serviced from the cached data. In typical proxy scenarios, the purpose of a proxy server is to fetch the requested resource from the remote server, return it to the requesting user, and cache it in local drives.
What is an anonymous proxy server?
Anonymous proxy does not transfer the information about the IP-address of its user, and thus effectively hide the information about you and your surfing interests. In addition, some proxies (the so-called elite proxies) can also hide the fact that a user surfing through a proxy server. So there are two types of anonymous proxies (see below).Anonymous Proxy server does not send HTTP_X_FORWARDED_FOR variable to host, this improves privacy since your IP address cannot be logged.
Elite proxy (high anonymity) does not send HTTP_X_FORWARDED_FOR, HTTP_VIA and HTTP_PROXY_CONNECTION variables. Host doesn't even know you are using proxy server and of course it doesn't know your IP address.
What is CoDeeN proxy?PlanetLab (CoDeeN) proxy - The PlanetLab Consortium is a collection of academic, industrial, and government institutions cooperating to support and enhance the PlanetLab overlay network. CoDeeN is an academic testbed Content Distribution Network (CDN) built on top of PlanetLab by the Network Systems Group at Princeton University. This testbed CDN consists of a network of high-performance proxy servers. Currently, proxy servers have been deployed on many PlanetLab nodes. These proxy servers behave both as request redirectors and server surrogates. They cooperate with each other and collectively provide a fast and robust web content delivery service to CoDeeN users. Note that all accesses via CoDeeN are logged, mostly to aid in identifying abuse and other forms of damage control. However, these proxies are good for browsing some Internet resources.
Configuring Your Computer to Access the HTTP Proxy Server
Internet Explorer 6.0:
- On the Tools menu in Internet Explorer, click Internet Options, click the Connections tab, and then click LAN Settings.
- Under Proxy server, click to select the Use a proxy server for your LAN check box.
- In the Address box, type the IP address of the proxy server.
- In the Port box, type the port number that is used by the proxy server for client connections (by default, 8080).
- You can click to select the Bypass proxy server for local addresses check box if you do not want the proxy server computer to be used when you connect to a computer on the local network (this may speed up performance).
- Click OK to close the LAN Settings dialog box.
- Click OK again to close the Internet Options dialog box.
- Click on Tools and select "Options" as shown below
- Click on the General tab and then the Connection Settings button.
