Registering http handlers within the same Application context

  1. Default Registering http handlers within the same Application context

    Hi all,

    In a custom control, I am saving something (image data, specifically) in the
    Application cache and then retrieving that data in my custom http handler.

    Question is where do I register this custom http handler?

    People have suggested that I register it in the "_layouts folder", but that
    results in my http handler getting invoked in a DIFFERENT application
    context. But, I want my http handler to be invoked right within the same
    application context.

    Thanks
    Praveen





  2. Default RE: Registering http handlers within the same Application context

    Hi Praveen,

    I built a similar sample and got same result with you. The web part doesn't
    share cached object with the HttpHandler since they are not in same ASP.NET
    application instance.

    I recommand you consider the suggetion I provide in another thread, put the
    the images files in a local folder. You can create a virtual folder so that
    the image files has a url, or get the image files directly in your http
    handler from disk. This solution increases the File I/O on the server, but
    consume less memory since we don't have cached object (Normally image
    caching may consume much memory in ASP.NET application). I think it is
    acceptable solution for current situation.

    If there is any further questions, please feel free to let us know.

    Sincerely,

    Luke Zhang
