Difference between Proxy and Firewall.

 

 

Now all your network traffic is passing through the proxy and it can alter it:

• It can replace the User Agent string with some meaningless string or strip out the referrers.
• It can accept all cookies, but not pass them to you, or it can block them altogether.
• It’s the proxy that’s connecting to the server, not you, so your IP isn’t disclosed.
• A proxy can be set up to work system-wide, so programs won’t be able to bypass it.

There are also some extra features that a proxy can provide:

• It can compress your traffic to save some bandwidth.
• It can cache files to give a little boost to page load times.
• It can strip ads from websites before they reach your computer.
• It can block malicious websites.

And finally, it can be used not only against filters, but also as a filter!
