CAS_ProxyChain:: (3 methods):
  __construct()
  matches()
  isSizeValid()


Class: CAS_ProxyChain  - X-Ref

A normal proxy-chain definition that lists each level of the chain as either
a string or regular expression.

__construct(array $chain)   X-Ref
A chain is an array of strings or regexp strings that will be matched
against. Regexp will be matched with preg_match and strings will be
matched from the beginning. A string must fully match the beginning of
an proxy url. So you can define a full domain as acceptable or go further
down.
Proxies have to be defined in reverse from the service to the user. If a
user hits service A get proxied via B to service C the list of acceptable
proxies on C would be array(B,A);

param: array $chain A chain of proxies

matches(array $list)   X-Ref
Match a list of proxies.

param: array $list The list of proxies in front of this service.
return: bool

isSizeValid(array $list)   X-Ref
Validate the size of the the list as compared to our chain.

param: array $list List of proxies
return: bool
