Http Headers

HTTP headers allow the client and the server to pass additional information with the request or the response.

IMan allows you to define headers at several levels of a request: authorisaton; webservice behaviour and the actual request.

Each level of the request takes precedence over the lower level, where the webservice behaviour headers of the same name will take percedence over the authorisation headers, and the request headers over the webservice behaviour headers.

Headers are added or deleted by clicking the add and icons respectively, existing headers can be edited by double clicking the relevant entry.
