Will Collect respect a 302 redirect on a file listed in the form manifest

The docs only say this:

<downloadUrl/> A fully qualified URI for downloading the media file to the device. It may be a valid http or https URI of any structure; the server may require authentication; the server may require a secure (https) channel, etc.

I could try it out but curious if anyone knows off-hand.

I don't think Collect respects redirects on submission because it's a security issue. I would guess it doesn't respect redirects on download, but you should absolutely try it out and report back.
