This class works just like LWP::UserAgent (and is based on it, by being a subclass of it), except that when you use it to get a web page but run into a possibly-temporary error (like a DNS lookup timeout), it'll wait a few seconds and retry a few times. It also adds some methods for controlling exactly what errors are considered retry-worthy and how many times to wait and for how many seconds, but normally you needn't bother about these, as the default settings are relatively sane.
