many/most webpages these days are heavily dynamic content, a static 
snapshot would likely break.  plus any site-relative links on that 
snapshot would be pointing to your server, not the original, any ajax 
code on that webpage would try to interact with your server which won't 
be running the right back end stuff, etcetc.
