[silva-dev] localization and caching, was: RE: caching for file and image assets

Hi Jose,

 just my two cents on caching and i18n:

 In the SMI it may be the case the same URI points to all the localized
versions, as localization may be done via Cookies; but in this case
simple caching by URL is not possible anyway

 For the public views I guess it is better to use prefixes to the URL or
something like that and not cookies or language preferences, as the
cookeis are not very reliable to work, and personally I feel the
language-preference may result in unexpected results for people having
a "wrong" configuration.

 If using URL-prefixes to determine the locale the URL's look different
for different localized versions of the same page, of course. I am not
comfortable enough with Zope's RAM cache manager to know it this helps
the caching to do the right thing.

Cheers,
