/* PHP 5.4 stores upload progress data only in the default session.
* After calling session_name(), we won't find the progress data anymore.
* The bug should be somewhere in
* https://github.com/php/php-src/blob/master/ext/session/session.c#L2342
* Until this is fixed, we need to load the default session to load the data.
* As we cannot load the phpMyAdmin-session after that, we will try to do
* an internal POST request to call ourselves in a new instance.
* That POST request grabs the transmitted upload data and stores them.
*
* TODO: The internal HTTP request may fail if the DNS name cannot be resolved
* or if a firewall blocks outgoing requests on the used port.
