HTTP transports
-
Dynamic Properties
or Properties
- Special configuration properties for the transport. Each transport type can contain custom properties
specified by the transport provider.
For the Advanced Edition: The properties are displayed as fields into
which you can enter values.
For the Advanced Single Server Edition: Enter the property names and their corresponding values
into the Properties area.
The properties are as follows:
-
Connection Backlog
or MaxConnectBacklog
- The maximum number of outstanding connect requests that the operating system will buffer
while it waits for the application server to accept the connections. If a
client attempts to connect when this operating system buffer is full, the connect request
will be rejected.
Set this value to the number of concurrent connections
that you would like to allow. Keep in mind that a single client browser
browser might need to open multiple concurrent connections (perhaps 4 or 5);
however, also keep in mind that increasing this value consumes more kernel
resources.
The value of this property is specific to each transport.
-
ConnectionIOTimeOut
or I/O Timeout
- The maximum time (in seconds) to wait when trying to read or write data DURING
a request.
The value of this property, after it is specified for the first transport, will be applied globally
to all other HTTP transports in this administrative domain.
-
ConnectionKeepAliveTimeOut
or Keep Alive Timeout
- The maximum time (in seconds) to wait for the next request on a keep alive
connections.
The value of this property, after it is specified for the first transport, will be applied globally
to all other HTTP transports in this administrative domain.
-
I/O Timeout
- See ConnectionIOTimeout
-
Keep Alive Timeout
- See ConnectionKeepAliveTimeout
-
MaxConnectBacklog
- See Connection Backlog
-
Maximum Keep Alives
or MaxKeepAliveConnections
- The maximum number of concurrent keep alive (persistent)
connections across all HTTP transports. (HTTP 1.1 allows multiple requests to be sent on the same TCP/IP connection.)
The default value is 90% of the maximum number of threads in the Web container
thread pool. This prevents all of the threads from being held by keep alive
connections so that there are threads available to handle new incoming connect
requests.
The value of this property, after it is specified for the first transport, will be applied globally
to all other HTTP transports in this administrative domain.
-
Maximum Requests per Keep Alive
or MaxKeepAliveRequests
- The maximum number of requests which can be processed
on a single keep alive connection.
The value of this property, after it is specified for the first transport, will be applied globally
to all other HTTP transports in this administrative domain.
-
Enable SSL
or SSL Enabled
- Whether to protect connections between the WebSphere plug-in and application server
with Secure Socket Layer (SSL). See also the security properties
-
External
- Whether this transport is for internal or external use
-
Host
or Host Name
or Transport Host
- The host IP address to which to bind for the transport
-
Host Name
- See Host
-
Port
or Transport Port
- The port to which to bind for the transport
-
Properties
- See Dynamic Properties
-
SSL Enabled
- See Enable SSL
-
Transport Host
- See Host
-
Transport Port
- See Port
-
Use global SSL default configuration
- See the general security properties
