Google PageRank mbpc

This module shows the PageRank of a website you define. Unlike other PageRank tools, this one caches the PageRank for the amount of seconds you define. Because of this cache, your website will not request the PageRank for every hit you get and so in theory this is faster and you won't stress the Google servers. Please note that this module only works if the php setting allow_url_fopen is turned on! Also the cache directory must be writable when using cache functionality.
