XsendFile loading has 0 bytes

Question

On the LAMP stack, I cannot get xSendFile to work. The problem is that downloads have 0 bytes.

To make sure xSendFile is installed, I added this to my file .htaccess:

<IfModule mod_xsendfile.c>
  SetEnv MOD_mod_xsendfile 1
</IfModule>

(I cannot verify this with apache_get_modules(), because I am running PHP as fastCGI.)

Then I have the following PHP code:

 if (1 != getenv('MOD_mod_xsendfile'))
    {
        echo 'mod_xsendfile is not installed';
    }
    else
    {
        $path = '/home/infar/';
        $file = 'hello.txt';
        if (file_exists($path.$file) && strlen($path.$file)>1)
        {
            if (true) // change to false to go around Yii
            {
                Yii::app()->request->xSendFile($path.$file,array(
                    'saveName'=> 'hello.txt',
                    'mimeType'=> 'plain/text',
                    'terminate'=> true,
                ));
            }
            else
            {
                //set proper Content-Type
                header('Content-Type: plain/text');
                //force download box with the filename hello.txt
                header('Content-Disposition: attachment;filename=hello.txt');
                header('X-Sendfile: $path.$file');
                exit;      
            }  
        }
        else
        {
            echo 'file not found at: '.$path.$file;
        }
    }

This code works as expected; from which I conclude that xSendFile should be installed and / or enabled. Then I run this script with both Yii xSendFileand simple PHP. In both cases, the download window opens, but always with 0 bytes.

I am at the end of my mind. What am I doing wrong?

In the interest of full disclosure, here is the relevant part httpd.conf:

<IfModule mod_xsendfile.c>
    XSendFile on
    XSendFilePath /home/infar
</IfModule>
