Issue:
We're running Policy Server and CA Access Gateway (SPS) 12.8
integrated with Azure for Single Sign-On, and we notice slowness in
responses in the browser, when processing HTTP headers.

How can we fix that ?
Environment:
Policy Server 12.8 
CA Access Gateway (SPS) 12.8
Cause:
A DNS server didn't work properly, which brings delays in the server FQDN resolution. 
Resolution:
Fixing a non responding DNS server from the resolv.conf file fixed the
issue.
