    I have the same problem just like Kathy.I take this from microsoft.public.dotnet.framework.aspnet.mobile Archive - April 2002

    Hi,
    I developed some mobile internet applications using
    mobile internet tool kit and ASP.net. During the testing
    process, I usually have to make several changes and re-
    access the pages several times in a short period of time
    to test these changes. I noticed that I usually get the
    old page instead of the updated one eventhough I did
    disconnect and then reconnect to the page from my phone.
    It seems like I have cache that keep the copy of the old
    page in my phone.
    So my question is do we have any way so I can script in
    my code to make sure that it will always give a updated
    page when user access it. In other words, to clear the
    browswer cache.

    I have tried every code or script,but it didn't work.I think the answer is related with machine config(answer number 1)just like Simon Calver said.
    I also take this from microsoft.public.dotnet.framework.aspnet.mobile Archive -April 2002

    Hi Kathy,
    Just some thoughts, to look into....
    which phone are you testing this with, is it one of those in the MMIT
    supported list? More specifically do you know the browser and version on
    this device?
    1. There are some properties in the browsercaps section of machine.config
    that are aimed to prevent caching: requiresUniqueFilePathSuffix - adds a
    unique random # to the URL query, to prevent caching in the gateway;
    supportsCacheControlMetaTag - adds the maxage=0 cache control to the meta
    tags in the response.

    Write a simple test page that you hit with your device and output the
    values of these properties using
    ((MobileCapabilities)Request.Browser).HasCapability("requiresUniqueFilePathS
    uffix", "true");

    2. some devices do have a means to clear the cache on the device, review
    the browser menu if you can, or if the device needs a hard reset.

    3. you may be able to output other META tags for cacheability. Review the
    ASP.NET Response.Cache.SetCacheability(HttpCacheability.Private)

    My question is how to setting that machine.config to prevent caching(answer number 1)because i dont't really understand about the answer.
    Can somebody help me explain the the detail of the answer?
    -Thanx-
