Owncloud PHP-FPM Redirect Loop Script Name Bug
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

The problem: | |
1) owncloud runs fine with apache 2.2 and finds itself in the environment | |
REQUEST_URI /index.php/apps/files | |
SCRIPT_NAME /index.php | |
PATH_INFO /apps/files | |
PATH_TRANSLATED /srv/www/htdocs/apps/files | |
PHP_SELF /index.php/apps/files | |
2) owncloud does not run with apache 2.4 maybe due to a different environment from mod-fpm | |
REQUEST_URI /index.php/apps/files | |
SCRIPT_NAME /index.php/apps/files | |
PATH_INFO /apps/files | |
ORIG_SCRIPT_FILENAME /srv/http/webspace/owncloud/index.php/apps/files | |
PATH_TRANSLATED /srv/http/webspace/owncloud/apps/files | |
PHP_SELF /index.php/apps/files/apps/files | |
