(Excel) Send XML REST Request, Get Response with No Body (Google Cloud Storage)

Demonstrates sending a RESTful XML request, and receiving a response where the expected response is a header with no body (Content-Length = 0). This example will create a bucket in Google Cloud Storage using the Google Cloud Storage XML API.

See Create a Bucket using the XML API for additional request options.
