Where is the constant for “HttpRequest.RequestType” and “WebRequest.Method” values in .NET?

System.Net.WebRequestMethods.Http
    .Connect = "CONNECT"
    .Get = "GET"
    .Head = "HEAD"
    .MkCol = "MKCOL"
    .Post = "POST"
    .Put = "PUT"

Ultimately, though; since const expressions are burned into the caller, this is identical to using “GET” etc, just without the risk of a typo.
