I have a networking question that I can't seem to understand since I only have basic networking knowledge.
My work has a HTTP proxy as most work places do, they use it to monitor and block traffic to certain sites and stop certain services from working etc.
What I'm confused about is I can access some services through the browser (e.g. chrome) but not locally on the computer. I can't understand why some stuff is getting blocked and in some instances it's not.
For example, I have chrome installed, and put in the correct proxy settings. I can go to google.com and log into gmail, calander and drive etc all through the browser. But when I try to setup sync in the chrome browser (for bookmarks and extensions etc) it doesn't work. Just can't authenticate. I don't see how the traffic would be different since it's going through the same application.
This is the case for skydrive, dropbox etc. I can access via the browser but applications are blocked even once I put the correct proxy details in.
Wouldn't the traffic be the same if it's through a browser or application? both would be https using port 443.
Also I just tired to ping google.com via CMD and it timeouts. So not sure why it gets blocked via CMD (proxy has been setup in internet settings).
I managed to get the dropbox application to work via the socks proxy our work has. (didnt work for google stuff though). So why does the sock proxy work and not the http proxy?
Sorry I know these are random questions I would just like to understand how it works.
