[Zope] i18n site and search robots

[Gilles Lenfant]

Hi,

This is not strictly speaking a Zope problem, but certainly lots amond you
faced and fixed this.
I made a i18n site with Localizer that runs fairly good, including its i18n
search engine.
But what about external searche engine robots (google, infossek...)
How to "tell" them that they may browse and index the pages in french,
english, spanish (...), changing their http header "Accept-Language" ?

Many thanks in advance
