<div dir="ltr">1. Its not a transparent proxy. <div><br></div><div>2. My clients get wpad configuration from AD server. So there are two question. </div><div> 2.1 :I know that wpad is used to identify proxy server and port(and rest other bypass rules). When clients resolve to <a href="http://wpad.abc.com">wpad.abc.com</a>, is there way that I can overwrite the wpad file off client. Like creating a webserver to to serve wpad file and I change /etc/hosts file to "<myhwebserveripaddress> <a href="http://wpad.abc.com">wpad.abc.com</a>"</div><div>2.2 Is there any other way to tell clients via squid server, to do not come to squid server and re initiate the request. </div><div><div class="gmail_extra"><br><div class="gmail_quote">On 24 July 2015 at 21:10, Jagannath Naidu <span dir="ltr"><<a href="mailto:jagannath.naidu@fosteringlinux.com" target="_blank">jagannath.naidu@fosteringlinux.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><br><div class="gmail_quote"><span class="">On 24 July 2015 at 21:05, Jagannath Naidu <span dir="ltr"><<a href="mailto:jagannath.naidu@fosteringlinux.com" target="_blank">jagannath.naidu@fosteringlinux.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Dear List,</div><div><br></div><div>I have been working on this for last two weeks, but never got it resolved. </div><div><br></div><div>We have a application server (SERVER) in our local network and a desktop application (CLIENT).
