Tunneling proxy may have various meanings; but most time, this refers to socks proxy. As the name suggests, socks proxy use sock 4 or 5 protocol, which performs at an intermediate layer between the presentation layer and the transport layer. Socks (tunneling) proxy can be used for any form of TCP or UDP socket connection. This means it can be used for most application software (in addition to http connections), e.g., instant messenger.  

Open proxy may have different interpretations, e.g., some geeks deem web-based proxy as open proxy; others may confuse open proxy with unauthentic proxies. Open proxy usually is similar to web-based proxy (e.g., using http protocol), but there are some differences. Web-based proxy retrieves resources for the client, and at the same time some modifications were also made. For example, most web-based proxy scripts rewrite the java script and act as client directly. But most open proxy only fetch the resources and do not make any modifications. Because open proxy uses http protocol for the connections between the client and the proxy server. This makes it different from tunneling, or socks proxy.  

Web-based proxy, some times called web proxy, usually refers to a type of proxy service through web servers. A client connects to the service provider's website (proxy server), then type the web address he/she wants to browse. The proxy server fetches the contents, and passes them to the client. By using web-based proxy, the client may access sites blocked by their local ISP or parents. For example, social networking sites, e.g., myspace and facebook, were blocked in some US and UK schools. The pupils may use web-based proxy to bypass the blocking and access these sites. Similarly, in some countries, the internet is censored for various purposes. Some users in these countries may also use web proxy to access the blocked sites. Some users use web proxy for privacy considerations, and they do not want to disclose their IP info to such untrusted sites. In this case, their info will very likely only be recorded in the proxy server. Web-based proxy usually is powered by a few proxy scrips, including CGIProxy, PHProxy, Glype, Zelune and Surrogafier.

In WWW world, proxy usually refers to the intermediary that retrieves information from other sources (e.g., websites) for the client. This is sensible when: the client cannot directly connect to the resources, e.g., some ISPs' firewall blocks these resources erratically or deliberately; the client does not want to disclose his/her info (e.g., IP address) to the resources There are different types of proxy: web-based proxy, open proxy and tunneling.
