I have a web application that sends an XML POST from the browser and I am using Fiddler to capture the body of the XML being sent out to ensure that the proper information is being sent from the application. I can see the POST to localhost:12345 captured in Fiddler, but when my co-worker clicks on the TextView tab in the Inspectors it is empty. This works fine on my machine and I am able to view the XML information in the TextView tab. This also works as expected for some of my other co-workers so it seems to be something specific with her machine that is interfering with the request. I observe this behavior whether she is connected to VPN or in the office using the network directly it doesn't appear to be an issue with the VPN.
We are using IE to view this information and my co-workers and I are using versions 10 and 11. I have looked at both setups (on my machine and my co-worker) and they are identical. Settings in my Connections tab for Fiddler Options are set to port 8888, allow remote computers to connect, reuse client connections, reuse server connections, act as a system proxy on startup, monitor all connections and <-loopback>; as a bypass for Fiddler. I tried to remove the loopback on my co-worker's machine but that did not resolve the issue. The gateway is set to use system proxy and HTTPS is set to capture and decrypt for all processes.
I have also had her try running Fiddler as an Admin and tried disabling the anti-virus programming we have on our company-issued laptops but neither of those seemed to have worked. Is there something else I'm missing here? Thanks.
