Google & Rest
• REST – Representational State Transfer
• Architectural style for web service
• Google says “REST is simple, lightweight, scalable,
and maps very well to representing and exposing
data.”
• Is it REST? – Joe Gregorio (XML.com)

Http response code & Exceptions
Throw your own exception
HttpWebResponse response = authResponse as HttpWebResponse;
if (response != null)
{
int code= (int)response.StatusCode;
if (code != 200)
{
throw new GDataRequestException("Execution of
authentication request returned unexpected result: "
+code, this.Response);
}

Service Level
Questions
Statefulness
When you use SOAP to set a server value,
does the server respond correctly in the
subsequent states?
Access
Can an unauthorized user successfully access
a control that only the administrators are
authorized to use?
Response time
Is the Web service taking too long to respond
(for example, more than 10 seconds)?
Time-out
What happens when the Web service times
out?
Versioning
Can a new build break an existing Web
service's functions?
Have we learned anything from this?
