Question:

HTTP Download - ensuring asynchronous in a web session

Sep 19 '12 at 12:59

I am using the HTTP Download functionality to download files during a web request. It seems that if I use a loop download more than one file, the thread detaches from my web session. Is there something I can do to ensure the downloads always remain in the active thread?

I don't understand the question. Maybe a code snippet showing what you are doing might help?

This is the code I'm running. If I step into it, then after the download, sometimes the debugger starts jumping back and forth between this loop and code that happens after it.

Chilkat.Http http = new Chilkat.Http();
    if (http.UnlockComponent("30-day trial"))
    {
        bool isError = false;
        string localPath = string.Empty;
        foreach (RemoteImage remoteImage in remoteImages.ImageList)
        {
            localPath = Path.Combine(imageDownloadFolder, Path.GetFileName(remoteImage.Url));
            if (!http.Download(remoteImage.Url, localPath))
            {
                //Log errors
            }
            else
            {
                remoteImage.LocalPath = localPath;
            }
        }

        if (isError)
            return Types.RemoteImageProcessingStatus.error;
    }

It appears to have been caused by breakpoints in my source. If I remove the breaks it works fine. Thanks.
