# Display Online Help

You can display the HTTP Connector Reference by sending an action from your web browser. The HTTP Connector Reference describes the actions and configuration parameters that you can use with HTTP Connector.

For HTTP Connector to display help, the help data file (`help.dat`) must be available in the installation folder.

To display help for HTTP Connector

1. Start HTTP Connector.

2. Send the following action from your web browser:

       http://host:port/action=Help

   where:

   `host` | is the IP address or name of the machine on which HTTP Connector is installed.
   `port` | is the ACI port by which you send actions to HTTP Connector (set by the `Port` parameter in the `[Server]` section of the configuration file).

   For example:

       http://12.3.4.56:9000/action=help
