MIME Content Type in HTTP Headers - They don't exist for TIFF images

Question

Hello,
I think this may be a bug...
In an effort to stop client browsers from attempting to render TIF images served up from UCM 11g, I would like to change the MIME Typte to: application/octet-stream
Supremely, a browser would see this in the HTTP header and simply provide the "OPEN or SAVE" dialog.
Seems easy enough - from the UCM Configuration Manager, I can set/edit all the mime types I want. I did set .tiff and .tif to application/octet-stream. Apparently Weblogic does NOT honor these settings.
When I click on a PDF file, I get: application/pdf
When I click on a TXT file, I get: text/plain
When I click on a TIF file, I get: NOTHING - no mime type specified in the HTTP header at all.
Does anybody know where in the stack of Weblogic/UCM 11g that mime types are set? Does anybody know why I'm not seeing ANY mime type when I click on a tif?
Please let me know.
Thanks!
JDM

Yeah, that does seem a bit unwieldy. Try the following instead:
Navigate to the "<Middleware_home>/user_projects/domains/<yourdomain>/config/" directory and there create the following file :
mimemappings.properties
In this file add the below mapping :
tiff=application/octet-stream
Save the changes , restart UCM server and then test to see if the issue still shows up .
