After you select a method and configure input and output ports, you must configure a URL. Enter a base URL, and the Designer constructs the final URL. If you select the GET or SIMPLE DELETE method, the final URL contains the base URL and parameters based on the port names in the input group. If you select the SIMPLE PATCH, SIMPLE PUT, POST or SIMPLE POST methods, the final URL is the same as the base URL.
You can use a mapping parameter or variable to configure the base URL. For example, declare the mapping parameter $$ParamBaseURL, enter the mapping parameter $$ParamBaseURL in the base URL field, and then define $$ParamBaseURL in the parameter file.
You can also specify a URL when you configure an HTTP application connection. The base URL specified in the HTTP application connection overrides the base URL specified in the HTTP transformation.
An HTTP server can redirect an HTTP request to another HTTP server. When this occurs, the HTTP server sends a URL back to the Integration Service, which then establishes a connection to the other HTTP server. The Integration Service can establish a maximum of five additional connections.
