Keep ’em lowercase. They’re DNS names, so while the should be case-insensitive, they are, in fact not. So if you’re getting 400s creating queues (since Bad Request is so helpful, an all) — make sure all of your queue names are lowercase.
Here are all of the queue naming rules, from http://msdn.microsoft.com/en-us/library/dd179349.aspx:
- Every queue within an account must have a unique name. The queue name must be a valid DNS name, and cannot be changed once created. Queue names must confirm to the following rules:
- A queue name must start with a letter or number, and can only contain letters, numbers, and the dash (-) character.
- The first and last letters in the queue name must be alphanumeric. The dash (-) character cannot be the first or last character. Consecutive dash characters are not permitted in the queue name.
- All letters in a queue name must be lowercase.
- A queue name must be from 3 through 63 characters long.
