PDF attachment content type "application/force-download"

When adding a PDF as attachment to a page, the content type of the attachment is usually set to application/pdf. However, sometimes it is set to application/force-download. In this case, the document is not displayed by the browser, the document is downloaded instead. It has to be changed to application/pdf manually to work as expected.

Does anyone know, how the content type for uploaded attachments is determined?

Hi Michael,

I hope you are using Firefox!

It seems to be a browser problem acording to the following similar references:

I do think there is a FireFox issue playing some role:
http://jsbin.com/ulamor/213/edit?html,css,console,output
FireFox returns "application/force-download" where Chrome and Safari both return "application/pdf"

Alright, this seems to be a Firefox "bug" (at least I'll refer to it as a bug, the developers don't) discussed in https://bugzilla.mozilla.org/show_bug.cgi?id=373621

 

You could try to use another browser to confirm that.

Kind regards,

Daniel P Santos

Yes, you're right. I verified it with Chrome and IE and both are working fine. So, I assume, we have to live with that. Thank's for pointing me in the right direction.

You are welcome Michael! We are here to help. :)

Hi,

I have exactly the same problem with Confluence and Firefox 38.2.1 on Mageia.

Thank's for your answer.
