On windows 7 and w10 clients we cant use fiddler as a web debugger because clients has websense endpoint installed. We made some tests but nothing happened. When endpoint proxy installed, application added its proxy address to the IE' use automatic conf. script section so traffic routes over this url (ex:http://pac.xxx.com/proxy.pac?=ajjndfd) .we dont edit this file. How can we handle this problem ? On fiddler, we changed gateway proxy address too. I hope you can help us asap. Thank you
