Amazon S3 Add METADATA to existing KEY
- by Daveo
In S3 REST API I am adding metadata to an existing object by using the PUT (Copy) command and copying a key to the same location with 'x-amz-metadata-directive' = 'REPLACE'
What I want to do is change the download file name by setting:
Content-Disposition: attachment; filename=foo.bar;
This sets the metadata correctly but when I download the file it still uses the keyname instead of 'foo.bar'
I use a software tool S3 Browser to view the metadata and it looks correct (apart from 'Content-Disposition' being all lower case as that's was S3 ask me to sign)
Then using S3 Browser I just pressed, then save without changing anything and now it works???
What am I missing how come setting a metadata 'Content-Disposition: attachment; filename=foo.bar;' from my web app does not work but does work from S3 Browser?
