#error_pattern(action, error_pattern) ⇒ Object

Adds a new error pattern. Patterns are analyzed in order of their definition. If one pattern hits the rest are not analyzed.

@xample:

error_pattern :abort_on_timeout,     :path     => /Action=(Run|Create)/
error_pattern :retry,                :response => /InternalError|Internal Server Error|internal service error/i
error_pattern :disconnect_and_abort, :code     => /5..|403|408/
error_pattern :disconnect_and_abort, :code     => /4../, :if => Proc.new{ |opts| rand(100) < 10 }
