[TYPO3-dev] Strange RealURL Problem

[Patrick Lobacher]

Hi Peter,

perhaps my description was not clear enough:

1.) I have (lets say) 30 diffent domains in one pagetree - each 
containing a proper domain records, pages, content, ... and - this is 
important - each of the domains have RealURL enabled

2.) The editor dont want to login into each of the domains typo3 link 
but in just one installation where he can edit all domains - This works 
of course. I will call this domain (where everyone logs in) the "preview 
domain" as all previews will be started from here (if you click "show" 
in the page tree). This can be a totally different IP adress (in our 
case) but it makes no difference if you take one of the metioned 30 domains.

3.) If you change something in the backend, then open your browser and 
type in the domain (where you have changed something) manually - then 
everythings works as expected - especially the RealURL generation of links

4.) But if you click the preview link ("show") you will be forwarded to 
the frontend with a link like 
http://www.typo3domain.com/index.php?id=pageid (where typo3domain.com is 
the domain where the typo3 backend is called from - the preview domain). 
Of course you will get the correct output - no problem. But the 
calculated RealURL rootpage_id is (in the most cases) wrong (and 
additionally stored in the DB too - so that the page couldn't be reached 
with the normal way too). If you clear the entry or change it manually 
to the correct one in the DB - everything works fine.

This happens because of the fact that:

- The calculation of the rootpage_id comes from the realurl config. In 
this config I am forced to specify a rootpage_id for every domain I want 
to use. Even if I disble realurl for the preview domain.

Something like:
$TYPO3_CONF_VARS['EXTCONF']['realurl']['www.typo3domain.com']['pagePath']['rootpage_id'] 
= 1;

- In this config I have to decide to which rootpage_id I want my preview 
domain connected. If I have 30 domains (with 30 rootpage_ids of course) 
I have to decide which of them I take

- Exact in the moment I preview a page the rootpage_id of the preview(!) 
domain will be saved together with the page_id. And this is in 29 of 30 
cases wrong (given that I habe 30 Domains in one page tree)


Now we are working on a setup, that realurl will completely disabled if 
the domain is the preview domain (ts condition). So if you enter a 
preview link you habe no realurl and so no wrong rootpage_id/page_id 
combination can be saved. If you view it from the domain name everything 
works fine with RealURL enabled.


Cheers
Patrick
