I have configured Pega Knowledge Helpsite on an anonymous Servlet ( with a technical operator ). The url generated from that configuration is working fine in my browser. I have implemented a button with an open URL action in our CSR app and it is working well, the helpsite is opened in a new tab.

But when I test the feature with an SSO operator, it is not working. It is opening CSR in the new tab instead of the helpsite. It is like the system is reading the first part of the URL and rederecting it to the operator session without considering the anonymous servlet.

I am quite perplex and I have no idear how to correct this behaviour in Pega.  

It seems that it is possible to have a custom session and an anonymous one open at the same time in the same browser

but it is not possible for an anonymous one and a SSO. 

Please feel free to suggest anything, as I am short of idear.

Thanks in advance
