I would like to know if there is any possibility to capture traffic from the IIS reverse proxy, since I would need to know how the HTTP packet headers have been modified through the proxy. Currently I use the fiddler to capture the traffic but it does not show me the changes of headers made by the reverse proxy, it only shows me the request generated by the browser and the IIS response.
