How do I get csv file to download on IE? Works on firefox

Question

I\'m struggling with an odd error. I have a simple web app that grabs stuff from a DB then outputs it as a downloadable csv file. It works on firefox and chrome, but IE fail

Answer 1

We have just had the same issue and after adding many headers and getting a working link I then removed them one by one and found the key one for us was "Cache-Control: public" so in the end we just had

header("Cache-Control: public"); 
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=some_filename.csv");

which worked fine.
