Connection Handler
This is an abstract object type that cannot be instantiated.
Connection Handlers are responsible for handling all interaction with the clients, including accepting the connections, reading requests, and sending responses.
Connection Handlers
The following Connection Handlers are available:
These Connection Handlers inherit the properties described below.
Connection Handler properties
You can use configuration expressions to set property values at startup time. For details, see Property value substitution.
| Basic Properties |
|---|
allowed-client |
allowed-client
Synopsis |
A set of clients who will be allowed to establish connections to this Connection Handler. |
Description |
Valid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. Specifying a value for this property in a connection handler will override any value set in the global configuration. |
Default value |
All clients with addresses that do not match an address on the deny list are allowed. If there is no deny list, then all clients are allowed. |
Allowed values |
An IP address mask. |
Multi-valued |
Yes |

Read-only |
No |
denied-client
Synopsis |
A set of clients who are not allowed to establish connections to this Connection Handler. |
Description |
Valid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. If both allowed and denied client masks are defined and a client connection matches one or more masks in both lists, then the connection is denied. If only a denied list is specified, then any client not matching a mask in that list is allowed. Specifying a value for this property in a connection handler will override any value set in the global configuration. |
Default value |
If an allow list is specified, then only clients with addresses on the allow list are allowed. Otherwise, all clients are allowed. |
Allowed values |
An IP address mask. |
