Using the image manager control on the telerik radeditor does not seem to function correctly in a web farm enviroment. It sometimes works and other times (most of the times) returns with the following error message:
 'You don't have permission to access this page or your cookie has expired!Please, refresh the page! "

However when adding a host entry on a client machine, the upload manager works gracefully.

Is there a setting or property on the radEditor such us there is on the spell check that passes all the data it needs via the HTTP Get querystring? If not how do you suggest we can resolve this issue without resolving to using 'sticky sessions'?

We are currently using an older version of the telerik control, we are using version 5.6. Does this issue also exists in the new versions of the telerik RadControls? If not we may consider purchasing a the newer version if there is no available fix with the current version.

Thanks you very much for any assistance.

Hi Sly,

Please, review the following help articles:

    -    Do RadControls use session state and/or cookies?
    -    Cookies and Session overflows with many Telerik controls.

If the provided suggestions in the following articles above do not help in your scenario, then I would highly recommend that you upgrade to the latest version 7.3.4 of RadEditor Classic or RadEditor for ASP.NET AJAX where this problem does not exist any more.

The latest version provides a new configuration for the way information is passed to the dialogs, avoiding the "session expired" message from the file browser dialogs. This functionality is set by default and you shouldn't set any properties to turn it on.


Kind regards,

Above mentioned links are not working. Could you please give me the correct URLs for these?

Hi Krishna,

We do not use cookies at our controls, unless the user configure such explicitly (for example if some data needs to be additionally persisted). By default, all resources needed for the controls in the ASP.NET AJAX suite are kept in the cache, but we provide option to store them in the Session. More details on the possible ways to configure your application in order to store/take the resources in/from the Session in the following blog post:
How to integrate RadControls for ASP.NET AJAX in a WebFarm or WebGarden scenario
