[TYPO3-english] Realurl broken after moving site to new domain

[Oliver Salzburg]

I made a site available under a new hostname. When I visit that site,
all rewritten URLs look like http://mysi.te/12/ (12 being the index of
the page). When I visit the site through the original hostname, the URL
rewriting works as expected.

What did I miss? In the end I only need the site to be available from
the single, new domain.

Thanks in advance

Oliver
