Area list information has not changed since the last search.
Note: The API client must provide the "plcm-area-list" representation's
ETag value in the "If-None-Match" HTTP header to ensure conditional retrieval.
This will improve network performance by reducing bandwidth consumption.
If the API client chooses to exclude an ETag value from a previous, identical
search in the "If-None-Match" header, then the HTTP response will contain the
search results in the message body.
The "plcm-area-list" ETag can be accessed from the initial search result's HTTP
response header. Also, subsequent searches require the identical search filter
to ensure an equivalent ETag value. This also assumes no other client made changes to
users on the server.
