I need to set the HTTP_X_FORWARDED_FOR value in the Request.ServerVariables collection. I’m trying with Fiddler (see this article).
So I set up a custom HTTP request:
GET http://myhost/ HTTP/1.1 http_x_forwarded_for: my.fake.ip.1, my.fake.ip.2 Host: myhost.
The request is correctly executed.
But when I debug the code, the Request.ServerVariables(“HTTP_X_FORWARDED_FOR”) is empty.
Where am I wrong?
Is Fiddler the correct tool?
The header you are sending should be
x-forwarded-for. TheRequest.ServerVariablesare exactly what it says server variables. It does not just contain the http headers sent in the request.When placing the header values into server variables IIS creates a name for the variable that is based on the header name but is not the name verbatim. It converts all characters to uppercase, replaces all
-with_and adds the prefix ofHTTP_to header name to create a server variable name. The prefix is added to prevent arbitary headers aliasing other fixed server variable names.
