== disable-http-lb-application

Disables an application managed by a load balancer

[[sthref1047]]

=== Synopsis

[source]
----
asadmin [asadmin-options] disable-http-lb-application [--help]
[--timeout 30]
--name application_name target
----

[[sthref1048]]

=== Description

The disable `disable-http-lb-application` subcommand disables an
application for load balancing. The disabled application goes offline
for load balancing with minimal impact to users. Disabling an
application gives a finer granularity of control than disabling a server
instance and is most useful when a cluster is hosting multiple
independent applications.

Once the application is disabled and the changes have been applied to
the load balancer, new requests for the application are not forwarded to
the target. Existing sessions continue to access the application until
the timeout is reached. This process is known as quiescing.

If an application is deployed across multiple clusters, use this
subcommand to disable it in one cluster while leaving it enabled in
others.

If an application is deployed to a single server instance, use this
subcommand to disable it in that instance while leaving the instance
itself enabled.
