Hi,<br><br>I have varnish 2.1.4 running for last 3 months, everything was working well, suddenly I got complaints from multiple users that they can not open the sites.<br><br>users are using ISA porxy to reach to internet, it seems issue when ISA and Varnish both are used, users made some test and reported as below.<br>
<br>1. If they do not use ISA proxy sites open perfectly (bypass ISA proxy)<br>2. If they do not use Varnish sites works well (bypass Varnish)<br><br>On firefox half of the page open, and on Chrome it says duplicate content-length error.<br>
<br>I am not sure why this happens when both ISA and Varnish are used.<br><br>Please let me know if anyone else encountered the same issue.<br><br>Thanks <br>
