How do you set Access-Control-Allow-Credentials CORS header

I see that SWIFT supports Access-Control-Allow-Origin and Access-Control-Allow-Headers, but how do you get it to send Access-Control-Allow-Credentials headers? Chrome preflight requests are failing to allow POSTs to SWIFT containers (with a policy) because ORIGIN pre-flight requests don't return an Access-Control-Allow-Credentials header.

How can I make SWIFT do this, when the ORIGIN request is on the container to which the user wants to upload?

Hi SyCode7, I did manage to get around the issues, but it was so long ago and I haven't looked at our on-prem swift deployment in so longer that I've forgotten the details. Here is what I have in my notes that I added to /etc/swift/proxy-server.conf:

` [filter:crossdomain]

use = egg:swift#crossdomain

cross_domain_policy = <allow-access-from domain=""/> `

However, I do remember making some other changes to the actual buckets I needed to be able to access -- I think I did the following:

`swift post xxxx --meta "Access-Control-Allow-Credentials:"

swift post xxxx --meta "X-Container-Meta-Access-Control-Allow-Origin:"

swift post xxxx --meta "Access-Control-Allow-Origin:"

swift post xxxx --meta "Access-Control-Allow-Headers:"

swift post xxxx --meta "Access-Control-Expose-Headers:" `

What I don't remember is whether I had to patch any of the swift code. I'm sorry it's been too long since I worked on this. -- Eric

Hi Eswenson, thanks for your response. I also resolved by following the instructions given here. The approach you described above didn't work for me i.e. specifying the information in the swift.conf file. many thanks though :)
