Here’s what you need to do.
Visit Google Translator and there you see under Translate 2 types of translations are mentioned in or.
1.text translator which u ignore just after or there is a website translator. Just write the website name(obviously the blocked site you want to visit) at the text box just bellow the text ” Translate a web page:“. In the language selector box select “French to English” or any language to english or English to English if you still want the site to be in english and then click on translate. Now the intended page in english will appear as if inside google translator not the actual webpage so now we indirectly accesed blocked site as this translator site which is unblocked acts as a proxy. Trick here is that the site intended is in english but we need to translate it to english b’coz we need the translator site act as proxy so we used French 2 English in that translator.
The output link was like http://translate.google.com/translate?u=http:/puzzlehacker.wordpress.com&langpair=fr|en which was from french to english as indicated by “langpair=fr|en” and the site mentioned after “u=” in the o/p link is the site intended which is http:/puzzlehacker.wordpress.com here. If we do from english to english we’ve to write “langpair=en|en” and if we intend to view blocked site orkut.com then u=http://orkut.com resulting in total link
http://translate.google.com/translate?u=http://orkut.com&langpair=en|en which can be used directly without visiting the translator sites. Due to this google translator is some times said as Google Proxy.
