Client IP Address in Load Balanced Scenario

Brenden Kehren asked on January 12, 2015 21:42

Does anyone know if this article is still pertinent in v8.x? I've been able to implement it in v7 without issue but it doesn't seem to be working in v8.x at all.

Thanks for following up Radek. After finally having a bit of time to debug further I found a simple change was needed in the last few lines to assign the actual address.

Old code:

if (!String.IsNullOrWhiteSpace(sClientAddress))
    RequestStockHelper.Add("UserHostAddress", sClientAddress);

New code:

if (!String.IsNullOrWhiteSpace(sClientAddress))
    RequestContext.UserHostAddress = sClientAddress;

The article is written and tested for version 7 only. We did not test it for any newer version. Anyways, the problem might be related to differences in API and project structure between Kentico 7 and Kentico 8. Could you please send us an e-mail to and refer to this forum thread? Thank you.

Best regards, Radek Macalik

We had to change one more line of code for 8.2 in the latest hotfix, instead of :

CMSRequestEvents.Begin.Before += new EventHandler<EventArgs>(SetClientAddress);


RequestEvents.Begin.Execute += new EventHandler<EventArgs>(SetClientAddress);

Not validated by Kentico, but I think that's the correct new method to handle this event.

Cheers, P.
