Header Creation service extension (Legacy)
ℹ️
This topic refers to legacy configuration syntax. App gateways are now defined as Proxy apps. A new example of the create header service extension is documented here.
Crafting custom HTTP headers is a common operation for legacy applications that consume identity via headers.
CreateHeader
This example uses the createHeader Service Extension to enrich the attribute data
returned in claims by an authentication provider.
