is there a way for me to pinpoint the location of this cache ?

Not if it's outside your control. If you run your favourite packet sniffer at the border of your network (ie. as far up the chain as you have access) that should show whether the cache is outside or not.

If wget is accessing a cache on the local linux machine, where would that cache be located ?

I'm not familiar enough with wget to comment, but I think that's highly unlikely anyway given you've been trying with different user agents on different client machines. A quick google shows that wget has a --cache option which can be set to "off" to bypass upstream proxies.
