To disable a port
1. Open Integration Server Administrator if it is not already open.
2. Go to Server > Ports.
3. Locate the port in the Port List, and click the
icon in the Enabled column to disable the port. The server displays a dialog box that prompts you to verify your action. Click OK to verify you want to disable the port. The server replaces the

icon with
No to indicate that the port is now disabled.
When you disable an HTTP/HTTPS port, Integration Server stops accepting new requests immediately. However, it allows all the in-flight requests to complete. Integration Server adds a Connection: close header field in the response header for in-flight requests, which indicates that Integration Server will close the connection after the in-flight request is complete.
For HTTP/HTTPS 1.1 requests, Integration Server always adds a Connection: close header field in the response header. For HTTP/HTTPS 1.0, Integration Server adds a Connection: close header field only when the client includes a keep-alive header field in the request.
