Comment 11 for bug 1091926

I confirm (that for me) the problem is proxy.pac related.

Up to now, I denied the access to www.mysite.com/proxy.pac for when users are outside, with their netbooks.

My Apache .htaccess looked like:

<Files proxy.pac>
 Order Deny,Allow
 Deny from All
 Allow from 192.168.0.0/16
</Files>

This worked for Chromium+IcedTea but not for Firefox+IcedTea.

Finally I had to use a new .htaccess like:

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REMOTE_ADDR} !^192\.168\.
RewriteRule proxy\.pac$ http://www.mysite.com/direct.pac [R=301,L]

where direct.pac is:

function FindProxyForURL(url, host) {
   return "DIRECT";
}

Finally, Chromium+IcedTea don't understand the possibility to return more than a proxy (or proxy fail).

I had a proxy.pac ending by:

return "PROXY 192.168.0.3:8080; DIRECT";

and I had to put:

return "PROXY 192.168.0.3:8080";
