REST Service cache problem

11-12-2008 8:21 AM |

Hello, I have a problem with astoria rest services (ADO.Net Data Services) and the cache

I am consuming a rest service basically a "select * from table" from my silverlight application.
My problem is that the result is always the same but i update the table.
Investigating with http monitor i realized tha the result is always from cache, that is the cause.
How can i clear the cache and always have a updated data?

In develop enviroment this problem didn't exist but now in production yes... i'm nervous... any suggestion is welcome

Thanks.

It doesn't seem to be a silverlight issue, If I were you I'd also post this question in a Data Services forum :)

Ugly response Confused

Ok.

Lesson 1
The most important options for working with data in Silverlight

1. SOAP
2. REST

Then, this can be a problem of interest for this forum.

I resolve the problem adding [QueryInterceptor("Element")] attribute on the server the for my query resources then for the implementation y write

OutgoingWebResponseContext outResponse = WebOperationContext.Current.OutgoingResponse;
outResponse.Headers.Add("cache-control", "no-store, no-cache, must-revalidate");
outResponse.Headers.Add("Pragma", "no-cache");
outResponse.Headers.Add("ROBOTS", "NOARCHIVE");

I hope that my experience will serve other to resolve this problem with which you can meet when develop Silverlight applications.

Thank you gabouy Cool
