I am new to Fiddler, but we are in a position where our current ERP (Dynamics AX 2009) is too old and does not support TLS1.2 (its built on .Net 3.5), therefore pretty much all REST calls do not function. Fiddler came up as an option to be able to override SSL protocols to TLS1.2--which in my proof of concept (installed locally to dev box) is working fine.
However I am a bit confused on how I can actually implement this in a "production-ready" manner as all the calls will come from individual client machines on our network running the AX thick-client (its a standard client/server architecture), so I would need to put this in place somehow to target/override/log only REST calls from this application to specifics hosts (I have this working via FiddlerScript) for any calls coming from our internal network. We would need all other traffic to not be impacted.
I'd prefer not to install Fiddler on every client machine, so does it make sense to stand it up as a proxy server between clients and firewall? Is there a better way?
