Caching support for URLs with port numbers

When mangling URLs of fetched data to store in the local cache, only
split on the first colon so that URLs with port numbers in them are
properly differentiated. Previously, all URLs for the same domain
name landed in a single file if a port number was included, causing
incorrect results to be returned from the cache.
