I want to upload a CSV file into our media library. In our Dev environment, this works as expected, the file uploads, shows up in the content tree, mime-type/extension is getting set appropriately, and I can attach/detach/download the file.

In our QA and Production environments, if I upload a CSV file, it gets added to the content tree and mime-type/extension is set appropriately. However, when whenever I select that item, the content editor kicks off a download automatically of that file and names it [SitecoreItemID].ashx.

I am thinking an IIS setting is different between the environments. Or maybe an old sitecore setting set long ago. Does anyone know what would cause this to occur?

UPDATE: I am only seeing this problem in IIS 7.5. Our DEV is running IIS 8.5 and it doesn't happen there.

according to the Sitecore documentation, the csv file is not supported.
