Chart in web farm often not displaying

I have followed the tutorial and have been able to display a chart using GetChart.aspx and either the Session, Cache or Httphandler methods described. I have only not tried the file method. After sometimes 5, sometimes 50 requests, the chart will not render and just a red x will be displayed. This will continue for many posts. Closing the browser and opening a new one will result in the image being displayed correctly the first time and then after a while the same problem occurs. This only happens on a web farm and not a single IIS server.

Hi DNxn,

Which exact TeeChart build are you using? Does this occur in any specific browser version?

Thanks in advance.

We were abe to reproduce the error with Microsoft's Session object so no longer consider this to be a problem with TeeChart. We will invetigate our web farm and may switch to using a database in the web farm to store session state between shared servers.
