Session error after upgrade to 15.0.13

[Davide]

Hello,

I recompiled an ISAPI project with the new IW 15.0.13 installed.
The previous release was compiled with IW 15.0.6 or IW 15.0.7 and worked fine.

The project include the frame navigation and some controls from CGDevTools.

When I try the 15.0.13 ISAPI dll on the server I get the following error:

Error message: The IP you are using is different than the one that initiated the session. 

Security check failed. Please restart the application.

Please note that depending on the actual exception that occured, restarting the application might not be possible. If this is the case, please report the error message to the administrator.

I encountered this kind of error some yeras ago on another application.
I remeber that could be related to some properties of the server controller but I remeber which?
Could you help me to solve this problem.

Thank you,
Davide

Hi Davide. In your ServerController, ObjectInspector->SecurityOptions->CheckSameIP := False;
