[squid-users] Squid for windows Very slow downloads of large files through squid with normal uploads

[Keith Hartley]

Yeah, there are some other considerations with this environment. While WSUS is the only service that downloads files in any significant quantity, there were architectural decisions made in the application that this environment hosts which requires the application to have some minimal internet access, which is what caused the need for the proxy. WSUS was originally set up exactly as you described until I learned of the application requirements, and technically it is the only thing that needs a proxy, but I didn't want to set up a different way of accessing the internet for each service that needed access and making it confusing, so went to using a proxy for everything so there would only be one path to the internet.

Writing rules at the network level would not be practical to implement even one time, let alone maintain over time. A more expensive firewall that is able to implement ACLs by hostname would be needed, and options for virtual firewalls hosted in Azure are limited. It would also require either implementing many static routes, or a transit network with a virtual router, and this environment will be supported by an organization that does not have a network engineer on staff.
It depends. If your make Internet access for servers due to updates - in most cases updates has limited distribution points (of course, we're not considering CDN now). Some cases can be easy solved by server's built-in firewall.

If we're talking about infrastructure, best solution for updates is internal updates server (like WSUS), which only have access to Internet with all security restrictions. You know this better than me ;) Anyway, centralized patch/updates server behind the border firewall is best solution.

But this is, of course, abstract discussion.

We're like it too, but Squid's itself is big and relatively complex software, requires much experience to use and not always easy in support. It has a lot of functions and can have very complex configurations. This is why I can't recommend use it in all cases requires proxying/caching without serious reasons.

Yes. Privoxy is very simple instead Squid. It is non-caching proxy, which have all functionality you require. It works with hostnames.

Don't worry - you will not require much support for it. It's just works. ;)
