As a simple workaround, I had my script send a newline character every 5 seconds or so to keep the connection alive.

Example:

set_time_limit(60 * 30);
ini_set("zlib.output_compression", 0);
ini_set("implicit_flush", 1);

function flushBuffers()
{
    @ob_end_flush();
    @ob_flush();
    @flush();
    @ob_start();
}

function azureWorkaround($char = "\n")
{
    echo $char;
    flushBuffers();
}

$html = '';
$employees = getEmployees();
foreach($employee in $employees) {
    html .= getReportHtmlForEmployee($employee);
    azureWorkaround();
}

echo $html;
