[TYPO3-core] FYI72: bug #9806: Mountpoints do not work across domain boundaries

[Dmitry Dulepov]

Hi!

This is SVN patch request.

Type: bug

Branches: trunk, 4.2

BT reference: http://bugs.typo3.org/view.php?id=9806

Problem: subpages of the mounted page will not be displayed if the
following conditions are met:
- config.typolinkCheckRootLine or
config.typolinkEnableLinksAcrossDomains is set
- page #1 is a mount point to a page #2
- page #2 has subpages
- subpages of the page #2 are accessed by clicking the menu

None of subpages to page #2 will be reachable from the current
domain. They will be prepended with the domain name of page #2. This
is incorrect because mounted pages always called from the context of
the current domain. TYPO3 detectes wrong linking and refuses to show
these pages.

The problem happens only in menu and only starting from TYPO3 4.2.0.

Solution: the attached patch fixes the issue. It tested on the
customer's site (including with and without RealURL). The issue is
critical for any site with mount points across domain boundaries and
must to come to the closest TYPO3 release.
