Definition
Allows cluster-wide NNTP caching.
Allows the Traffic Server to accept feeds of news articles from feed
or push groups.
If Traffic Server is clustered, configure your news server
CAUTION:
to send feeds to only one node in the cluster.
Feed and push groups are designated in the
file. The Traffic Server does not cache
nntp_servers.config
news articles from feed groups; instead, it receives feeds of news
articles as the parent NNTP server receives feeds. Push groups are
groups for which the Traffic Server can both retrieve articles on
demand and receive news feeds.
See nntp_servers.config‚ on page 177
designating news groups as push or feed in the
nntp_servers.config
Configures Traffic Server to log NNTP transactions in its event logs.
Configures Traffic Server to post NNTP articles to parent NNTP
servers in the background.

Traffic Server gets a cancel control message, it deletes the
corresponding article from the cache.
You do not need to enable this option if the Traffic Server is caching
articles on demand (if there are no feed groups). For all non-feed
news groups, the Traffic Server actively polls parent NNTP servers
for cancelled articles. See the Check for Cancelled Articles option,
below.

Sets the number of seconds that idle connections can remain open.
This timeout should be at least 3 minutes.
The Traffic Server regularly polls parent NNTP servers for new
groups. This option is the time period between checks. The parent
group lists change slowly, so you do not need to check them
frequently.
You must list the hosts you want to poll in the

nntp_servers.config
The Traffic Server regularly polls all non-feed news groups on the
parent NNTP servers for cancelled articles. This option is the
amount of time between checks. Checking for new articles should
not be done too frequently as it involves communication with the
parent NNTP server.
The Traffic Server regularly polls the parent NNTP server for new
