URI Parameters

The following additional parameters may be specified on the request URI.

 

Parameter Description

Optional. The timeout parameter is expressed in seconds. For more information, see Setting Timeouts for Queue Service Operations.

Request Headers

The following table describes required and optional request headers.

 

Request Header Description

Authorization

Required. Specifies the authentication scheme, account name, and signature. For more information, see Authentication for the Windows Azure Storage Services.

Date or x-ms-date

Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authentication for the Windows Azure Storage Services.
