module: netscaler_service
short_description: Manage service configuration in Netscaler
description:
    - Manage service configuration in Netscaler.
    - This module allows the creation, deletion and modification of Netscaler services.
    - This module is intended to run either on the ansible  control node or a bastion (jumpserver) with access to the actual netscaler instance.
    - This module supports check mode.

version_added: "2.4.0"

                Before forwarding a request to the service, insert an HTTP header with the client's IPv4 or IPv6
                address as its value. Used if the server needs the client's IP address for security, accounting, or
                other purposes, and setting the Use Source IP parameter is not a viable option.

                Name for the HTTP header whose value must be set to the IP address of the client. Used with the
                Client IP parameter. If you set the Client IP parameter, and you do not specify a name for the
                header, the appliance uses the header name specified for the global Client IP Header parameter (the
                cipHeader parameter in the set ns param CLI command or the Client IP Header parameter in the
                Configure HTTP Parameters dialog box at System > Settings > Change HTTP parameters). If the global
