Running CA Access Gateway (SPS), the browser receives the error:
Request URI: /
Error Type: SPS Exception
Error Code: WebAgentException
Error Message: Web agent has thrown error. More details in SPS logs.
No FQDN used for the host defined in the proxyrules.xml.
SiteMinder protection is based on cookies, and domain names.
As such, use full FQDN in configurations including the domain names, instead of just the host names.
Modify the proxyrules.xml with forward action, and ensure that all machines are referred by the FQDN:
<nete:proxyrules xmlns:nete=http://server1.example.com debug="no">
<nete:forward>
https://server2.example.net$0
</nete:forward>
</nete:proxyrules>
That will make all requests to the SPS, to be forwarded in the backend to https://server2.example.net.
