web-based 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.

- + : A leading plus sign indicates that this word must be present in every object returned.
- - : A leading minus sign indicates that this word must not be present in any row returned.
- By default (when neither plus nor minus is specified) the word is optional, but the object that contain it will be rated higher.
- < > : These two operators are used to change a word's contribution to the relevance value that is assigned to a row.
- ( ) : Parentheses are used to group words into subexpressions.
- ~ : A leading tilde acts as a negation operator, causing the word's contribution to the object relevance to be negative. It's useful for marking noise words. An object that contains such a word will be rated lower than others, but will not be excluded altogether, as it would be with the - operator.
- * : An asterisk is the truncation operator. Unlike the other operators, it should be appended to the word, not prepended.
- " : The phrase, that is enclosed in double quotes ", matches only objects that contain this phrase literally, as it was typed.
