While I went through homework 2, I came up with the following two
questions (I hope they have not been yet discussed in the recap
session):
1. How explicit do the message have to be when we write
package lists. Is it enough, to write in order to show the purpose of
the package or more explicit?
2. In Task 2.2 (Using Proxy), why does user2 need to get IP of proxy? From my understanding, proxy IP's are hard-coded on the end systems which are supposed to use them, to automatically "redirect" their traffic to them. They way it is used here, it reminds me more of a VPN gateway (although, I am a bloody beginner when it comes to proxies & vpns).
Thank you in advance!
Hi Devrim,
1. It is enough to write the purpose of the packet (there is no specific format) as long as it is clear. For example, 'request index.html'.
2. I don't know if all proxy's IP are hard-coded on the end system honestly. But at least in this question we assume not. As for proxy vs vpn, a proxy acts more like a vpn except that it is specific to redirect web requests. Whereas, a vpn anonymously redirect all your network traffic.
Are my answers clear to you?
Hey, thanks for the answers! Concerning the second point, I will just assume they are not already known to the client.
