Add Proxy-Authorization header in swagger

Question

I need to add specific header on swagger ui using .net core. Is there any way to include header like this?

Already tried:

• implementing IOperationFilter:

  public void Apply(Operation operation, OperationFilterContext context)
  {
      if (operation.Parameters == null)
          operation.Parameters = new List<IParameter>();
  
      if (operation.Parameters.All(p => p.Name != "Proxy-Authorization"))
      {
          operation.Parameters.Add(new NonBodyParameter
          {
              Name = "Proxy-Authorization",
              In = "header",
              Description = "Proxy-Authorization token",
              Required = true,
              Type = "string"
          });
      }
  }
  

• adding security definition:

  options.AddSecurityDefinition("Proxy-Authorization", new ApiKeyScheme()
  {
      In = "header",
      Description = "Please insert Proxy Authorization Secret into field",
      Name = "Proxy-Authorization",
      Type = "apiKey"
  });
  

Both didn't work. When I change header name everything work fine, but this specific header is wiped out from a call.

Did you ever meet this issue? How to solve this?

From: https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name

A forbidden header name is an HTTP header name that cannot be modified programmatically; specifically, an HTTP request header name.

...

Forbidden header names start with Proxy- or Sec-, or consist of one of these:

• Accept-Charset
• Accept-Encoding
• Access-Control-Request-Headers
• Access-Control-Request-Method
• Connection
• Content-Length
• Cookie
• Cookie2
• Date
• DNT
• Expect
• Host
• Keep-Alive
• Origin
• Proxy-
• Sec-
• Referer
• TE
• Trailer
• Transfer-Encoding
• Upgrade
