[TYPO3-dev] Multidomain setups and crosslinking - concept

[Steffen Kamper]

Hi,

i try to understand the concrpt of crossdomain-linking in TYPO3. There 
are some things that look more like bugfixes than like a concept.

The following parts are in the game when using multi domains:

* domain records
* config
* * baseURL
* * absRefPrefix
* * typolinkEnableLinksAcrossDomains
* * typolinkCheckRootline

*point 1* for me i don't understand:
typolinkEnableLinksAcrossDomains enables typolinkCheckRootline
typolinkEnableLinksAcrossDomains is used in a section where 
typolinkCheckRootline has to be set. So typolinkEnableLinksAcrossDomains 
  is only something to enable typolinkCheckRootline, why this both and 
what is the difference?

*point 2* - domain record seems not be respected, imho this should be 
the first url-part used

*point 3* - usage of baseURL and/or absRefPrefix - IIAC baseURL should 
be set, both can be a problem, absRefPrefix is needed for fully 
qualified urls for pictures and other ressources

*point 4* following doesn't work proper:

- Menus all use actual domain
- linking to page in other menu using element browser always use actual 
domain

please comment/add/correct this issue, thx.
