[Mechanize-users] Error trying to reload serialized page

What is the correct way to serialize an HTML page gotten from Agent::get, and
then to reload the serialized page back into Mechanize?  I tried the following
code:
	agent = Mechanize.new
	p1 = agent.get(url)
	=> #<Mechanize::Page ? >

	p2 = Mechanize::Page.new(p1.uri.to_s, p1.response.to_s, p1.body)

and got the error:
	Mechanize::ContentTypeError Exception: Mechanize::ContentTypeError

I also tried:
	p2 = Mechanize::Page .new(p1.uri, p1.response, p1.body)

and got the error:

A String is not an acceptable substitute for a Net::HTTPResponse or Hash
(representing the headers of a response).
> I also tried:

Try:

  p2 = Mechanize::Page.new p1.uri, p1.response, p1.body, agent

While Mechanize::Page defaults all these to nil, this doesn''t actually
work for Page.  I''ll see what I can do to fix this.

A Mechanize instance is consulted to determine how <meta> tags should be
found, so you must pass it in.
