cancelling a "fix cache key" action

is it possible to cancel a "fix cache key" action, since it didn't synchronized cache directory and database as expected :

Read DIR_FS_SQL_CACHE from configure.php: /var/www/.../cacheDOCUMENT_ROOT
Found SESSION_WRITE_DIRECTORY in database: /var/www/.../cacheDOCUMENT_ROOT

the /var/www/.../cacheDOCUMENT_ROOT should be /.../cache

in my configure.php file, I have written :

   define('DIR_FS_SQL_CACHE', $_SERVER['DOCUMENT_ROOT'] . "/shop/cache"); 
```as suggested by my hosting provider (they have upgraded servers lately)

and not 

define('DIR_FS_SQL_CACHE', '/var/www/.../shop/cache');

Thanks for any help !

Fwed

just FYI, I have found in the hosting provider phpinfo that :
_SERVER["DOCUMENT_ROOT"] = /

so I have modified my configure.php to :

define('DIR_FS_SQL_CACHE', '/shop/');  
```(should it be : *define('DIR_FS_SQL_CACHE', **'shop/**'); * ?? )

but still doesn't work ...

Something odd about what your Hoster said. Using _SERVER["DOCUMENT_ROOT"] can be helpful but not likely in this case.

Can you say what Control Panel is used for your Hosting account?
When you FTP into your Hosting account and go as high as you can in the dir. structure, do you see a dir. called 'public_html' and/or a dir. called 'www'?

You could also compare these 3 settings in a PHP info output:

_SERVER["DOCUMENT_ROOT"]
_SERVER["SCRIPT_FILENAME"]
_SERVER["PATH_TRANSLATED"]

All 3 should start the same for at least 3 directories.

Mind you, all of the above could be out the Window if your Hosting account is on a Windows Server.
