You see the code below, how I did use the session variable;
So the three questions are:

  1. Where are they stored? (Server or Client side)
  2. Are they unique for each web page visitor?
  3. Can I remove it using ajax or simple js code when my job is done with it? or it will be removed automatically..?

.

sbyte[][] arrImages = svc.getImagesForFields(new String[] { "CustomerName", "CustomerSurName" });

Dictionary<string, byte[]> smartImageData = new Dictionary<string, byte[]>();
int i = 0;
foreach (sbyte[] bytes in arrImages)
{
    smartImageData.Add(fieldNames[i], ConvertToByte(bytes));
    i++;
}

Session.Add("SmartImageData", smartImageData);

    Read more about sessions here. To answer your questions:

    1. Depends on your configuration (in-process, Session State Server etc.), but always server-side.
    2. Yes, each visitor gets a unique cookie.
    3. You can remove it client-side by removing the session cookie (usually ASP.NET_SessionId), or server-side by calling Session.Abandon(). Also, a session times out after a certain (configurable) period of inactivity.
