Hi
I got a problem with my svc service in asp.net site. I do file
uploading in iframe and the same time do calls to svc service to check
the uploading progress.
The problem is that service does not start processing of the request
until file is fully uploaded.
I checked forums for "concurrent service calls" and found
ServiceBehavior and CallbackBehavior settings there. I also written a
test page and test service to process two calls
simultaneously. Mentioned
settings don't help and I heed advice!
Below is my svc service
Below is my svc service
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(InstanceContextMode=InstanceContextMode.PerSession, ConcurrencyMode=ConcurrencyMode.Multiple, UseSynchronizationContext=false)]
[CallbackBehavior(ConcurrencyMode=ConcurrencyMode.Multiple, UseSynchronizationContext=false)]
public class MessageService
{
[OperationContract]
public string GetFileUploadsProgress(string MessageID)
{
System.Diagnostics.Debug.WriteLine("GetFileUploadsProgress - begin {0}", MessageID);
System.Threading.Thread.Sleep(1000);
System.Diagnostics.Debug.WriteLine("GetFileUploadsProgress - end {0}", MessageID);
//return S;
return MessageID + " - Ok";
}
|
there is how I call it:
function serviceCall() {
MessageService.GetFileUploadsProgress("test", updateProgress);
}
function updateProgress(result) {
document.getElementById("progress").innerHTML += "<br>" + result;
} |
On the test page I have a button. I quickly click it three times and
look at firebug console.
Results always come with reply time around 1sec, 2sec, 3sec. That mean the service
calls ALWAYS synchronously go one by one. The third reply waits for previous two to finish.
What should I do to make service answer on requests regardless on
other calls, posting pages and so on???
Please help!!!!
