Scenario 4:
Content
Routing
(SA7220 and
SA8200/
SA8220 only) Because the SA8220 can differentiate servers according to their
content, it can apportion requests based on the type of content
requested. For example, an administrator might choose to run the
most processor-intensive processes (such as CGI scripts) on the most
powerful servers while placing the less processor-bound files on
slower servers. The SA8220 then sends requests for CGI scripts to
the faster servers, thus avoiding the slowdowns that would occur if
the slow servers were relied upon.
