I have a machine setup to run automated tests. I have some software, including Fiddler running as scheduled tasks on start up without user required to log in. I can see tests passing, which means traffic goes through Fiddler, as they would fail otherwise. When I log in to that machine, I can see in Task Manager Fiddler running as background process.
But nowhere I can see the traffic. Fiddler is running as background process and I can't find the folder where it stores temp files. I have also tried setting autosave to a file every 5 minutes. And while it works when I run fiddler in UI, no sessions are saved when it runs as background process.
