Introduction

This is a server side redis module. Its use case is to automatically delete a key from redis when the corresponding client disconnects.

Commands

ax.associate_key

Syntax: ax.associate_key <key>

Associates an existing key with the current client session. When the client disconnects they key gets automatically deleted.

If the key is already associated with a client, this association gets transferred to the current client calling the command.

If the key gets deleted / expired/ evicted the association is automaticlly cleared.

Return Values:

• 0 if the key did not exist.
• 1 on success.
