> How can i change the language of my website
"... The requested language is determined by the 'Accept-Language'
field in
the HTTP header, but this selection can be overwritten
programmatically
by requesting a specific file, for example:
1 T.force('it-it') ..."
If you want to let the user choose its language by clicking in a link
or button. Your controller could use the force() method with the
option retrieved clien-side. (i.e. with a SQLFORM.factory() object or
simply a list of urls with arguments)
