WebUpdating an origin configuration’s shield configuration does not purge or modify content cached on the initial shield POP. However, it may result in a temporary increase in bandwidth as content is cached at the new location. This cache fill occurs when the new shield POP handles traffic that has not been previously cached at that location. WebDerivation (parse) tree The tree structure shows the rule that is applied to each nonterminal, without showing the order of rule applications. Each internal node of the tree corresponds to a nonterminal, and the leaves of the derivation tree represent the …
