+ | A unique name can be set for sockets to simplify the selection of the socket for sending out. For example, the rr and path modules can use the socket name to advertise it in header URI parameter and use it as a shortcut to select the corresponding socket for routing subsequent requests. | ||
+ | |||
+ | The name has to be provided as a string enclosed in between quotes after the **name** identifier. | ||

+ | Note that there is no internal check for uniqueness of the socket names, the admin has to ensure it in order to be sure the desired socket is selected, otherwise the first socket with a matching name is used. | ||
