Colleagues, I just can’t configure Fiddler to intercept http traffic from the .jar application, I already force the proxies into the JVM and force-feed them with the batch file, it doesn't help anything, it just ignores my requests ... (I’m not able to find the answer on the Internet

  • docs.telerik.com/fiddler/configure-fiddler/tasks/… - Sergey
  • How in the application from .jar http traffic is created. Is the library applied to the JVM proxy or system proxy settings? In extreme cases, you can use fiddler instead of wireshark. In addition, in any case there may be problems intercepting traffic to the loopback interface (127.0.0.1 or localhost) - Sergey
  • Sends a GET request to the site, accepts the response and performs the action. - JuniorD
  • @Sergey all that on winpcap`e intercepts the request successfully, but I do not know how to change it there on the fly, as Fiddler does. - JuniorD

    In this case, it is important how the connection to the site is opened. Fiddler works as a proxy, as I understand it. So the program should instead connect to the proxy fiddler proxy. If the program uses a library for http, which understands the proxy, then the instructions should be obtained. And if we suppose a socket is opened and http is already running over it, then nothing will work with fiddler. Unless there is no transparent proxy mode (transparent proxy). - Sergey
