Doc Text:	.Ceph Object Gateway internal HTTP headers are no longer sent while transitioning the object to Cloud Previously, some Ceph Object Gateway internal HTTP header values were sent to the Cloud endpoint, when transitioning the object to Cloud. As a result, some S3 cloud services did not recognize the headers and failed the transition or failed to restore the operation of the objects. With this fix, internal HTTP headers are not sent to Cloud and transitioning to Cloud works as expected.	Story Points:	---

Description Soumya Koduri 2025-02-10 19:23:18 UTC

Description of problem:

This is for the epic https://jsw.ibm.com/browse/ISCE-1472 

While validating cloud-restore feature with PoINT archival S3 gateway emulator, it was found that GET request fails with 403 error due to below reason -

Currently PAG does not alphabetically sort unknown query parameters before calculation the signature of the request. As a result the calculated signature differs from that the S3 client software has calculated before sending the request and this causes that the request is rejected.

PAG server might fix this issue but meanwhile, since these headers are custom and internal to RGW, they are not needed and can be omitted while fetching object from external cloud-service.
