I wanted to try the example here
http://www.codeconscious.com/rebol/rebol-net.html#HTTP
print read/custom http://babelfish.altavista.com/translate.dyn reduce ['POST {text=REBOL+Rules&lp=en_fr}]
Since the page has changed since I modified it to
write clipboard:// read/custom http://babelfish.altavista.com/translate.dyn reduce ['POST {trtext=hello+world&lp=en_fr&btnTrTxt=Translate}]
It does return an html page but it doesn't contain any translation. What did I miss thanks ?
