Using URL manipulation allows you to customize the URL of the image location that is in the response object.
For the following API operations the DICOM service returns the fully qualified URL of the image location in the response object under a DICOM tag (UR) in the response object.
Here's an example of a fully qualified image location URL. The URL could be found in the standard response for a STOW operation for a DICOM service that has data partition enabled, with partition name "foo".
https://localhost:63838/v2/partitions/foo/studies/1.2.826.0.1.3680043.8.498.13230779778012324449356534479549187420/series/1.2.826.0.1.3680043.8.498.77033797676425927098669402985243398207/instances/1.2.826.0.1.3680043.8.498.13273713909719068980354078852867170114
The preceding URL consists of three parts:
https://localhost:63838
(the hostname of DICOM service)v2/partitions/foo
(the path that represents the version of DICOM service being used and the datapartition name, if enabled)studies/1.2.826.0.1.3680043.8.498.13230779778012324449356534479549187420/series/1.2.826.0.1.3680043.8.498.77033797676425927098669402985243398207/instances/1.2.826.0.1.3680043.8.498.13273713909719068980354078852867170114
This feature allows you to customize the path of the image URL, if directed by the client, based on the request headers provided.
The modified URL is based on following two headers.
X-Forwarded-Host: The domain name of the original host (the one the client requested before the proxy or load balancer handled the request). For example: X-Forwarded-Host: www.example.com
X-Forwarded-Prefix: the original URL path or prefix that was part of the client’s request before the proxy forwarded or changed the request. For example: X-Forwarded-Prefix: /prefix
These headers are a part of .NET core standard forwarded headers.
If x-forwarded-host
header is present in the request object, it replaces the host name with the value provided.
If x-forwarded-prefix
header is present in the request object, it replaces the path with the value provided.
Here are the details of a request header for a STOW operation with the forwarded headers:
An example of a DICOM tag with VR = UR for a STOW operation when the forwarded headers aren't provided is shown below.
https://localhost:63838/v2/partitions/foo/studies/1.2.826.0.1.3680043.8.498.13230779778012324449356534479549187420/series/1.2.826.0.1.3680043.8.498.77033797676425927098669402985243398207/instances/1.2.826.0.1.3680043.8.498.13273713909719068980354078852867170114
An example of a DICOM tag with VR = UR for a STOW operation when the forwarded headers are provided is shown below.
