[Salesforce] IE8 cannot be downloaded. Can not connect to Internet solution

If you are trying to accomplish this task (getting a CSV file to download in IE8)Using salesforce.com(In which case your front-end is visualforce and you can't set all of the headers, only some of them), here's what you need:

<apex:pagecache="true"contentType="application/octet-stream#myAwesomeFileName.csv"showHeader="false"sidebar="false"standardStylesheets="false"><apex:outputTextvalue="{!csvContent}"escape="false"/></apex:page>

The key pieces here arecache=true, Which, in conjunction with the defaultexpires=0Attribute, achieves the following headers:

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");header("Cache-Control: public");

And thencontentTypeOfapplication/octet-stream--- Doingtext/csvFails for ie8.
