For indexing all pages of such servers, `VaryLang` command is used. It specify list of languages separated by spaces. These languages will used for indexing URL with multi-language versions.

Usage example:

    VaryLang "ru en fr"

`index` will fetch all document copies in Russian, English and French languages.
