ERR_CONTENT_LENGTH_MISMATCH

[lazzyms]

I am trying to convert html to pdf, on a Click action I want to download the pdf generated in browser.
$pdf->send('report.pdf');
throws this error : ERR_CONTENT_LENGTH_MISMATCH.
While this works fine : $pdf->saveAs('report.pdf');

Backend : PhalconPhp

This sounds very much the same like this issue: #270. Can you verify if you also have mod_deflate enabled?
