Azure Storage - Create session

Declaration

<AMAZURESTORAGE ACTIVITY="create_session" ACCOUNTNAME="text" ACCESSKEY="text (encrypted)" PROTOCOL="text (options)" TIMEOUT="number" BLOBENDPOINT="text" QUEUEENDPOINT="text" TABLEENDPOINT="text" PROXYTYPE="text (options)" PROXYSERVER="text" PROXYPORT="number" PROXYUSERNAME="text" PROXYPASSWORD="text (encrypted)" />

Description:

Creates a unique session in which to attach subsequent Azure Storage activities to. This allows a single task the ability to execute numerous Azure Storage operations that exist in multiple sessions simultaneously. To end a session, use the End session activity.

Practical Usage

Commonly used as a means of organizing and encapsulating a collection of related activities required to accomplish a particular task or process. The use of sessions can ensure consistency and eliminate redundancy.
