    Weird behavior with proxy DIRECT and no proxy setting in Internet Explorer




      We have a weird issue.


      We have some sites that are altered when modifying the proxy settings in Internet Explorer.

      We have MCP installed on computers to intercept all traffic to ports 80 and 443.


      When unchecking all proxy settings, the following sites are fine.

      When setting a proxy pac file returning DIRECT (so the same as no proxy), the sites are broken (altered or messed up).


      With MCP, it should be the exact same behavior. You can test it easily of you have MCP.


      Some samples sites:




      This behavior is occurring only on IE 10 and 11.


      What could be the issue?
