An RTMP distribution is similar to a web distribution, but an RTMP distribution streams media files using the Adobe Real-Time Messaging Protocol (RTMP) instead of serving files using HTTP. </p> <p>To create a new web distribution, submit a <code>POST</code> request to the <i>CloudFront API version</i>/distribution resource.

With previous versions of the API, we discovered that it was too easy to accidentally delete one or more values for an element that accepts multiple values, for example, CNAMEs and trusted signers. Our changes for the 2012-05-05 release are intended to prevent these accidental deletions and to notify you when there's a mismatch between the number of values you say you're specifying in the <code>Quantity</code> element and the number of values specified.</p> </important>",
