[TYPO3] RealUrl, multidomain, multilanguage, single tree setup 2

[Tomas Mrozek]

1. If your site is showing different language content despite the 
TypoScript condition then your problem is in your TypoScript setup and 
it wouldn't work even without RealURL, as Dmitry pointed out.

2. You don't want preVars in your URLs since you want to choose language 
according to domain, not the preVar. Therefore, there's no need to 
definy preVars for RealURL in the localconf.php.

3. You most probably need to have set $_GET['L']. Otherwise, RealURL 
will create links from page titles of default language. Therefore, 
SOMETHING must set the variable.
I am not sure what would be a good approach. I used to solve it by 
adding folowing to the localconf.php:

if(preg_match('/english_domain\.com/', $_SERVER["HTTP_HOST"])) {
   $_GET['L'] = 1;
} else if(preg_match('/german_domain\.de/', $_SERVER["HTTP_HOST"])) {
   $_GET['L'] = 2;
} // else $_GET['L'] is not set, so it's default, Slovenian
