I want to monitor HTTP traffic between a process on my local machine and another (server) process, also running on my local machine.
How can I configure Fiddler to
.NET and Internet Explorer don't send requests for localhost through any proxies, so they don't come up on Fiddler.
Many alternatives are available
Use your machine name instead of localhost. Using Firefox (with the fiddler add-on installed) to make the request. Use http://ipv4.fiddler instead of localhost.
