Web service calls
to Web service functionality.
You learned how Microsoft created an HTML component to encapsulate Web service calls. This
component reads Web service information from a WSDL file and develops a friendly object
to handle the requests and responses.
You also learned how Mozilla is still developing its Web service functionality. It provides a low-level
SOAP API and also WSDL proxies. Issues of cross-domain security and advanced privileges are also dis-
cussed as they relate to Web services.
Lastly, you were introduced to a cross-browser Web service solution that, although not pretty, can pro-
vide a common interface for use in both Internet Explorer and Mozilla.
