Table 1–60 http-listener Attributes
Attribute |
Default |
Description |
---|---|---|
none |
The unique listener name. An http-listener name cannot begin with a number. |
|
none |
IP address of the listener. Can be in dotted-pair or IPv6 notation. Can be any (for INADDR_ANY) to listen on all IP addresses. Can be a hostname. |
|
none |
Port number on which the listener listens. Legal values are 1 - 65535. On UNIX, creating sockets that listen on ports 1 - 1024 requires superuser privileges. Configuring an SSL listener to listen on port 443 is standard. |
|
none |
(optional) Specifies the external port on which the connection is made. |
|
inet |
(optional) Specifies whether the IP address is an inet or ncsa address. |
|
false |
(optional) If true, enables blocking on both the external and listener ports. |
|
1 |
(optional) Number of acceptor threads for the listener, typically the number of processors in the machine. Legal values are 1 - 1024 . |
|
false |
(optional) Determines whether the listener runs SSL. To turn SSL2 or SSL3 on or off and set ciphers, use an ssl subelement. |
|
none |
References the id attribute of the default virtual-server for this particular listener. |
|
none |
Tells the server what to put in the host name section of any URLs it sends to the client. This affects URLs the server automatically generates; it doesn’t affect the URLs for directories and files stored in the server. If your server uses an alias, the server-name should be the alias name. If a colon and port number are appended, that port is used in URLs the server sends to the client. If load balancing is enabled, use the server name of the load balancer. |
|
none |
(optional) If the listener is supporting non-SSL requests and a request is received for which a matching <security-constraint> requires SSL transport, the request is automatically redirected to the port number specified here. If load balancing is enabled, use the redirect port of the load balancer. |
|
true |
(optional) If true, X-Powered-By headers are used according to the Servlet 2.4 and JSP 2.0 specifications. |
|
enabled |
true |
(optional) Determines whether the listener is active. |
