Figure 3.12 A.sample.of.a.Web.site.view.in.a.browser.
something.interesting,.at.least.to.a.forensics.geek.like.myself..
There.are.a.lot.of.references.to.other.URLs,.to.pictures,.to.
actions,.to.videos,.and.so.forth,.that.are.not.showing.up.as.
I.look.at.the.Web.site.in.its.normal.view..Now,.why.would.
that.be?
Well,. it. is. because. of. what. we. talked. about. earlier.. The.
Web.site.developer.and.browser.designers.want.you.to.enjoy.
your.experience,.so.they.include.everything.that.you.will.ever.
need.to.access.in.this.source.coding..And.guess.what?.The.
browser.loads.all.of.that.data.into.your.cache.ile.so.it.will.be.
easier.and.quicker.to.access.when.you.ask.for.it..Is.that.not.
thoughtful.of.them?
But. this. brings. up. some. interesting. considerations. when.
we. discuss. the. data. stored. and. available. on. your. computer.
that.show.your.Internet.activity..Think.about.that.for.a.minute.
using.the.example.page..In.Figure 3.12,.you.see.part.of.a.Web.
site—the. home. page. for. Comcast.net,. and. in. Figure 3.13,.
you.see.some.of.the.source.code.for.that.same.page.
What. I. want. you. to. notice. when. you. look. at. these. two.
illustrations. is. the. fact. that. although. there. is. a. lot. of. data.
showing. on. the. Web. site. that. you. look. at,. there. are. many.
items.noted.in.the.source.code.which.you.do.not.see.on.the.
page..A.very.interesting.one.that.you.see.referenced.a.lot.in.
this.sample.graphic.are.cookies..We.spend.some.more.time.
