Integration Platform Technologies: Siebel Enterprise Application Integration > Web Services > About Custom SOAP Filters > About Handling Custom Headers Using FiltersSOAP headers provide the option of providing optional or mandatory processing information. To process optional custom headers that are provided by external applications, a special business service known as a filter may be defined. Filters can process both request and response headers. A special attribute, mustUnderstand, is used to indicate whether or not the custom header is to be processed:
You want to keep the SOAP body and header processing isolated. The inbound dispatcher and outbound proxy know how to process the SOAP body, but do not know how to set or consume headers. Headers are application-specific. Some customization is needed to set and consume custom headers. To process optional custom headers that are provided by external applications, a special business service, a filter, is defined. You can configure the Web Service outbound proxy and the Web Service inbound dispatcher to call specific filters for the processing of individual (custom) headers. NOTE: Headers that are consumed by the filter service have to be removed from the SOAP message. |
