Typo3 multidomain with ssl: TOO_MANY_REDIRECTS

Question

using typo3 4.5/extbase 1.3 i am trying to run my shop extension in a multidomain environment: the shop page should be run on a HTTP domain A and the following checkout process on a HTTPS domain B. Domain B is https://www.ssl-id.de/[domainA] (host is Strato). I therefore have set:

two page trees with both roots having an domain entry of domain A and domain B respectively
the checkout page in the HTTPS page tree have set "Use protocol" to HTTPS
the TS:baseURL is set conditionally to domain A or domain B (based on the ENV:HTTP_HOST)
the realurl configuration is set for both domains (with $TYPO3_CONF_VARS['EXTCONF']['realurl']['[domainA]'] and $TYPO3_CONF_VARS['EXTCONF']['realurl']['www.ssl-id.de'])

Unfortunately the redirect from the HTTP shop to the HTTPS checkout leads to Error 310 (net::ERR_TOO_MANY_REDIRECTS) in chrome. The network report says

Request URL:https://www.ssl-id.de/[domainA]/de/checkout.html?FE_SESSION_KEY=bc04cd0f5b835bcbdd8c475bafb037f7-ab3700f6a9fae520b75981130b31ec77&cHash=6d7e7195735947b09becbfa9c26c8bf0

which reads as "The target page url does not exist, please look at the same url again". When using a second HTTP url instead of the HTTPS url, the setup works well. When calling the checkout page directly without redirect from the shop page, the result is the same error 310.

The .htaccess is a quite standard typo3-realurl .htaccess:

AddDefaultCharset utf-8

AddType video/mp4 mp4
AddType video/mp4 m4v
AddType video/ogg ogv
AddType video/webm webm
AddType video/webm webmv

<FilesMatch "\.(js|css)$">
  <IfModule mod_expires.c>
    ExpiresActive on
    ExpiresDefault "access plus 7 days"
  </IfModule>
  FileETag MTime Size
</FilesMatch>

<IfModule mod_rewrite.c>

RewriteEngine On
#RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)\.(\d+)\.(php|js|css|png|jpg|gif|gzip)$ $1.$3 [L]

RewriteRule ^(typo3/|t3lib/|fileadmin/|typo3conf/|typo3temp/|uploads/|favicon\.ico) - [L]

RewriteRule ^typo3$ typo3/index_re.php [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule .* index.php [L]

</IfModule>

Any suggestions on how to remove the redirect problem or how to get closer to the caller of the redirect that leads to the infinite loop?

The problem has been host (Strato) specific: Their SSL Proxy does not send the relevant $_SERVER['HTTPS'] which somehow makes typo3 go crazy.

The solution is setting $_SERVER['HTTPS'] yourself by adding the following lines to the end of your localconf.php:

if ($_SERVER['HTTP_X_FORWARDED_HOST'] == "www.ssl-id.de") {  
    $_SERVER['HTTPS'] = 1;  
}

or more general

if (this_is_a_ssl_request()) {  
    $_SERVER['HTTPS'] = 1;  
}
