The links don't seem to be working. Although, if you only type in the IP, the hotmail page comes up. What's up with this?

When you receive a link in a Hotmail message, it gets routed through a redirect link...

If you strip off the hotmail header, you're left with the following, working, link:
http://www.cisco.com/offer/iptgameplan/V691-100-EX

Pretty neat, huh?

Hi guys.

Okay, Skipster...I gotta ask! I can see how you extracted the link, but what are is the stuff like %2f for? And is the word action the redirector?

beenframed,

After rereading my post, it presents itself like I was being an @ss with the "What's up with this?". Sorry if it came off that way, I should have typed something like, "Whoa...that's weird that Hotmail is giving away Cisco books." (I don't understand the redirector thing yet)

Anyway...thanks for the great link! I took the test, filled out a questionaire and the book is on it's way! Thankyou very much!

Ok... A quick lesson in URL reverse-engineering!

1) "http://64.4.43.7/cgi-bin/linkrd" is the address of the redirector script at Hotmail
2) "?" marks the start of the query string being submitted along with the redirect request.
3) "_lang=EN" means Language=English
4) "&" is the parameter separator
5) " lah=a2e15dcd8750b28d5ea2944c59
cfdc9a" I have no idea, except that it must be an internal token of some kind used for authentication
6) "lat=980643998" again, some kind of internal token
7) "hm___action" the action the redirector is supposted to take, identifying the link to redirect to
8) "http%3a%2f%2f" is simply the URL-encoded form of "http://" (the ":" became a %3a since that is the hex representation of the ASCII value for ":". Similarly, each "/" became a %2f.
9) "www%2ecisco%2ecom" is nothing more than "www.cisco.com" where each "." was translated into %2e, it's hex ASCII value
10) "%2foffer%2fiptgameplan%2f" is "/offer/iptgameplan/" because %2f represents a "/"
11) "V691%2d100%2dEX" is "V691-100-EX" because %2d represents "-"

Since the redirect link includes tokens that only allow the owner of the mailbox to access the link, we simply bypass the redirector entirely, un-URL-encode the argument that contains the encoded URL at cisco.com, and bingo, we have our fully functional stand-alone URL: http://www.cisco.com/offer/iptgameplan/V691-100-EX
