Issue/Introduction



We'd like to understand how works the CA Access Gateway (SPS) in comparision with
the Web Agent.  When there isn't an agent on the external webserver, the user should
go to the CA Access Gatway instead. So it looks like the IP-address of
the URL corresponding to the website should be changed to an address
which is recognized by our CA Access Gateway on which rules for this
website are defined which controls the authenication and autorisation
of the website.  If the authentiaction is accepted then the user must
be redirected to the external website otherwise the user is rejected.

Is this the correct implementation for protecting an external website with
CA Access Gateway instead of using a webagent?

Environment

Release: MSPSSO99000-12.8-Single Sign-On-for Business Users-MSP
Component:

Resolution

At first glance, you understood fine how the CA Access Gateway (SPS)
works. The CA Access Gateway (SPS) is a Reverse Proxy. It works with
an embedded Web Agent to protect your application. But instead of
running the application on the CA Access Gateway (SPS), the CA Access
Gateway (SPS) will forward the request to the backend application.

So said, the url :

http://myserver.mydomain.com/myapp 

from your older Web Agent, will be kept the same as per your new CA
Access Gateway (SPS).

But the IP to which it will resolve will be the one of the CA Access
Gateway (SPS) instead of the older Web Agent.
