[TYPO3-mvc] Cache/CHash issue with realURL and Multi Language Domains

[g4-lisz at tonarchiv.ch]

Hi there!

Since we switched our site to language dependent multi domain there's an 
issue with our extension...

We are usign 3 languages with 3 domains

L=0 => www.defaultdom.ch
L=1 => www.frenchdom.ch
L=2 => www.italiandom.ch

The realurl_conf.php looks like this:

<?php
$TYPO3_CONF_VARS['EXTCONF']['realurl']['_DOMAINS'] = array(
         'encode' => array(
                 array(
                         'GETvar' => 'L',
                         'value' => '0',
                         'useConfiguration' => '_DEFAULT',
                         'urlPrepend' => 'http://www.defaultdom.ch'
                 ),
                 array(
                         'GETvar' => 'L',
                         'value' => '1',
                         'useConfiguration' => '_DEFAULT',
                         'urlPrepend' => 'http://www.frenchdom.ch'
                 ),
                 array(
                         'GETvar' => 'L',
                         'value' => '2',
                         'useConfiguration' => '_DEFAULT',
                         'urlPrepend' => 'http://www.italiandom.ch'
                 ),
         ),
         'decode' => array(
                 '/^(www\.)?defaultdom\.ch$/' => array(
                         'GETvars' => array(
                                 'L' => '0',
                         ),
                         'useConfiguration' => '_DEFAULT'
                 ),
                 '/^(www\.)?frenchdom\.ch$/' => array(
                         'GETvars' => array(
                                 'L' => '1',
                         ),
                         'useConfiguration' => '_DEFAULT'
                 ),
                 '/^(www\.)?italiandom\.ch$/' => array(
                         'GETvars' => array(
                                 'L' => '2',
                         ),
                         'useConfiguration' => '_DEFAULT'
                 ),
         ),
);

On one page we embedded a pluign twice with different Controller/Action. 
They both use the same object type in it's action argument:

     public function spitalinfoAction(Tx_Hplusinfo_Domain_Model_Klinik 
$klinik) { ... }
and
     public function infoAction(Tx_Hplusinfo_Domain_Model_Klinik 
$klinik) { ... }

The realURL mapping looks like this:
$TYPO3_CONF_VARS['EXTCONF']['realurl']['_DEFAULT'] = array(
                 'init' => array(
                         'enableCHashCache' => '1',
                        ..............,
                  ),
                 'pagePath' => array(
                         'type' => 'user',
                         'userFunc' => 
'EXT:realurl/class.tx_realurl_advanced.php:&tx_realurl_advanced->main',
                         'spaceCharacter' => '-',
                         'segTitleFieldList' => 
'tx_realurl_pathsegment,title',
                         'languageGetVar' => 'L',
                         'rootpage_id' => '1',
                 ),
                 'postVarSets' => array(
                         '_DEFAULT' => array(
                                 'spital' => array(
                                         0 => array(
                                                 'GETvar' => 
'tx_hplusinfo_fe_spitalinfo[klinik]',
                                         ),
                                 ),
                                 'action' => array(
                                         0 => array(
                                                 'GETvar' => 
'tx_hplusinfo_fe_spitalinfo[controller]',
                                                 'noMatch' => 'bypass',
                                         ),
                                         1 => array(
                                                  'GETvar' => 
'tx_hplusinfo_fe_spitalinfo[action]',
                                                  'noMatch' => 'bypass',
                                         ),
                                 ),
                         ),
                 ),

With this a URL looks like http://www.defaultdom.ch/results/spital/233/ 
(<- tx_hplusinfo_fe_spitalinfo[klinik]=233)

Now when this links opens in the browser and we switch to another 
klinik.uid e.g.
    http://www.defaultdom.ch/results/spital/45/
then some content of the page (spitalinfoAction) are still from 
tx_hplusinfo_fe_spitalinfo[klinik]=233, others (infoAction) are updated 
to tx_hplusinfo_fe_spitalinfo[klinik]=45

When i set 'enableCHashCache' = 0 then it works as long as the CHash is 
appended to the URL...

Before switching to multi language URL 
$TYPO3_CONF_VARS['EXTCONF']['realurl']['_DEFAULT'] was looking 
absolutely the same.
And CHashCache was working properly.

I'm totally screwed - any help will be much appreciated!

Cheers,
T
