DOMPDF Attachment issue in IE (Internet Explorer)

dompdf ie DOMPDF Attachment issue in IE (Internet Explorer)I have used DOMPDF in my project. But I was facing problem with Attachment. In FireFox it was working fine. But in Internet Explorer (I used IE 6) it ended with an error. In IE it was showing the download dialogue box offering the script page I used to generate the PDF file. When I tried to download the file it showed an error.

I searched the web and found no suitable solution. I followed the instruction given in http://www.corenettech.com/blog/ but it didn’t work :(. But I got an idea from this post. I started digging the code and have done following changes to PDFLib_Adapter class (available in DOMPDF_DiRECTORY/include/pdflib_adapter.cls.php).

I have removed the following line (line 829):

header("Cache-Control: private");

and added

if (strstr($_SERVER['HTTP_USER_AGENT'], "MSIE"))
{
     header('Expires: 0');
     header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
     header("Content-Transfer-Encoding: binary");
     header('Pragma: public');
     header("Content-Length: ".strlen($data));
}
else
{
     header("Cache-Control: private");
     header("Content-Transfer-Encoding: binary");
     header('Expires: 0');
     header('Pragma: no-cache');
     header("Content-Length: ".strlen($data));
}

After

header("Content-type: application/pdf");
header("Content-Disposition: $attach; filename=\"$filename\"");

That’s it! My code started working :).

Hope this will save your time of surfing the net ;).
