[TYPO3-english] Cache multiple versions of site

[Christian Lerrahn]

Hi,
I have a site that uses several domain names. Now I would like all of
them to show the same content without redirecting back and forth
between the domain names. However, when I set a base tag, the cache
will only use that one. When I don't use a base tag, I will get a
weird mix of domain names. Is it possible to share content in between
domain names and cache separately?

In other words, I want to serve a different page for
http://www.server.com/abc.html than for http://www.server.net/abc.html
even though the contents are served from the same page in TYPO3. Can I
do that? Even better would be a slight modification (via TS?) somewhere
to avoid Google penalties.

Cheers,
Christian
