HttpClientHandler.AllowAutoRedirect Property
Gets or sets a value that indicates whether the handler should follow redirection responses.
Assembly: System.Net.Http (in System.Net.Http.dll)
Set AllowAutoRedirect to true if you want the handler to automatically follow HTTP redirection headers to the new location of the resource. The maximum number of redirections to follow is set by the MaxAutomaticRedirections property.
If AllowAutoRedirect is set to false, all HTTP responses with an HTTP status code from 300 to 399 are returned to the application.
The Authorization header is cleared on auto-redirects and the handler automatically tries to re-authenticate to the redirected location. In practice, this means that an application can't put custom authentication information into the Authorization header if it is possible to encounter redirection. Instead, the application must implement and register a custom authentication module.
