HP WebQoS Peak for the Zeus Web Server
Configuring HP WebQoS for Zeus
When redirection is disabled, the following types of web pages can be
served:
Domain Redirect the rejected session to the domain to which the
systems in the cluster belong. For example, if the cluster
consists of the two systems ww1.sales.acme.com and
ww2.sales.acme.com, specify the domain as
.sales.acme.com. Note the leading dot.
The domain specifies the scope over which the client-side
cookies can be shared (HP WebQoS uses client-side cookies
to encode session information).
Group The cluster group to which this system belongs.
TTL Time to Live. The number of redirections allowed before
rejecting the session. Add one to the TTL parameter to get
the number of redirects. For example, setting the TTL to 0
allows one redirection. Setting the TTL to 1 allows two
redirections.
It is recommended that the TTL be set to a value no larger
than 2.

Rejected Sessions
Parameter Description
Error The “Error 503 Service Unavailable” error message is served

way to respond to a rejected request. Extra load on the system
may be generated by users trying to immediately re-establish a
connection.
