3.3.5.1.1 Handler Execution

A handler is a software component on the server that examines an incoming request and takes one of two possible actions: disallows the request or makes transformations to the request. When the handler disallows a request, the server SHOULD<76> close the HTTP connection. Sending server information in the response can pose a security risk.

The server can choose to execute the default handler if the rdsHandlerString is VT-EMPTY or is the empty string (VT-BSTR BSTRNULL).
