What additional abilities does a CGI proxy have?
Unlike other types of proxy servers CGI proxies have considerably wider abilities as for information filtering. They can: – Prohibit execution of active content (scripts) on a page – JavaScript, etc. – Prohibit (or to leave only for itself, without passing to a client) cookie files – Encode URL to which a request is addressed. For example, your request to the www.yahoo.com through CGI proxy in an address bar you will see something like that: http://www.cgi-proxy.com/abcd104dflsjuywe34sdfispd345klksfdsl So a system administrator viewing server logs with analysis purposes can not determine what server you have reached (www.sex.com or www.altavista.com).
