Caching Problem?

Hi all

I am developing an ASP.NET application for PDA that must permit the access
to the MapPoint.Net WebService.

Now I have this problem:

When I load a Map the first time it shows good.

The second Time i select another map it shows me the old map and not the
new.

I am using a Session to store Map Bitmap. And using tag <mobile:Image> to
show the picture. Using response.binaryWrite to send bitmap to the client.

Reading the WebServer Logs, I notice that the PDA made only te request to
the server to obtain the page containing the image tag, but not the request
to obtain the image.

What can I do?

tks

It seems like the device is catching the image based on the url of the image
generated by the image control. One trick you can try is to generate some
random querystring appending to the image url specified in the href
attribute in the markup so the device would make new request for the image.

Yeah!

This is the correct solution.

I have just applied and running perfectly, for me!

Thanks
