2.2.7.7 Tunneled Requests

This section does not define a new request type, but rather defines an alternate way of representing Update Request Types (section 2.2.7.3) and Delete Request Types (section 2.2.7.4) by using a POST request and the X-HTTP-Method (section 2.2.5.8) request header. This alternative representation is often referred to as "POST tunneling".

This Tunneled Request type is fully defined through X-HTTP-Method header usage. As such, see X-HTTP-Method (section 2.2.5.8) for details regarding how the X-HTTP-Method header is used to create a Tunneled Request.
