An HTTP interceptor class must implement the com.softwareag.is.interceptor.HttpInterceptorIFC interface for inbound messages and the com.softwareag.is.interceptor.HttpOutboundInterceptorIFC for outbound messages.

You can register only one HTTP interceptor class of each type.

The HTTP interceptor class must provide implementations of the preProcess and postProces methods. For more information, see the webMethods Integration Server Java API Reference.

Using an HTTP interceptor delays the processing of a request. Any logic that the preProcess method executes to determine whether or not to continue with request processing needs to be done synchronously. However, if the preProcess method includes logic that can be done asynchronously by spawning another thread, regular processing can proceed without a delay.

Using an HTTP interceptor also delays the processing of responses.

An HTTP interceptor cannot modify the content of the HTTP request or response.

Integration Server passes a byte array representation of the input stream in the case of an inbound interceptor (or output stream in the case of an outbound interceptor).

Unless an HTTP interceptor throws an HttpInterceptorException to reject a request, Integration Server continues with the normal processing of the original input (or output) stream.
