9. The
images
rule we created selects all the requests for image files; now we need a rule to determine which
servers will receive all the other requests. The Default rule is not sufficient, and in fact we don’t want it to be
reached, since it could send a request for content to one of the image servers. So, we’ll create another rule with
the same match expression as the Default [
any
() ], but a restricted list of servers. This effectively replaces the
Default match rule with one of our own.

maintained by the applications that run on these servers.)
12. Select the
commit
button to save your changes to the
content
rule.
