I am trying to see if I can have a specific Hosts file that only a Proxy Server application on my machine will use while the remainder of the machine uses the normal proxy server.
For example, I want to take (and this is JUST AN EXAMPLE) www.cnn.com and map it to 127.0.0.1. However, I only want this to happen when connected to a proxy server application running on my machine.
Then I would configure Firefox to use the Proxy Server while IE doesn't use the Proxy server.
Could I use something like Fiddler, Charles, or some other Proxy/Debugger and have only that application use a custom Hosts file?
Why? This allows me to compare the live web site with what I have developed locally. Trust me, I need the host name mapping for a reason. I'm using HTML from the live site with local CSS changes. I need to compare those CSS changes to what is in Production environment.
