I see similar issues (broken images) when internal clients use a proxy (not squid, and not a caching proxy) to access internal (intranet) content, even though the same users do not get broken images when using the exact same proxy gateway to access public (Internet) content. > I think the problem is related to the problem of direct access to > intranet servers, but the problem solved when I set on the browser not > to access proxy for the domain "example.com".

We've 99% solved the problem by configuring internal web browsers to use a Proxy Automatic Configuration (PAC) script where possible -- all modern browsers can use PAC for deciding when/which proxy gateway to use, on a per-destination (by hostname and by URL) basis. To force the change onto all windows workstations, there are a number of ways you can push this configuration onto the desktop without manually visiting each seat in the enterprise. For OSX and other Unix users, we just supply screenshots for Firefox/Opera/Mozilla/Netscape/Safari/etc. Henrik Nordstrom wrote: > > Your denied requests were for a server running on an odd port. > Check your Safe_ports setting. What's interesting is that in my (not squid-specific) case, the proxy the users are "bouncing off" to get to internal resources is not configured to block requests to odd ports. Also, sometimes if the user hits reload often enough, the broken images will load successfully. I would be interested to know if John Mok has equivalent results? Kevin Kadow
