Recently I start using CloudFlare for my web site. After 1 day, I found that all pages with RadEditor failed to load the editor, displayed javascript error: Sys.InvalidOperationException. Some controls in Ajax Control Toolkit also failed as well.

Since CloudFlare works like a reverse proxy, I thought this is the cause. Disable the service for this site worked around the problem, but how to make RadEditor work under reverse proxy?

Hello,

The problem is most likely due to that the proxy server is cashing the handlers and makes them invalid. For this reason the controls are unable to load their scripts and resources and do not work.

To fix it you can exclude the Telerik specific handlers from the proxy caching OR use enable the CDN scripts as explained in the following help article: CDN Overview, e.g.

<telerik:RadScriptManager
    ID="RadScriptManager1"
    runat="server">
    <CdnSettings TelerikCdn="Enabled" />
</telerik:RadScriptManager>


All the best,
