This method parses the given content and returns a map of

Note: Meta-redirects should be followed only when they are coming from
the original URL. That is:
Assume fetcher is in parsing mode and is currently processing
foo.bar.com/redirect.html. If this url contains a meta redirect
to another url, fetcher should only follow the redirect if the map
contains an entry of the form <"foo.bar.com/redirect.html",
Parse
with a ParseStatus
indicating the redirect>.
