In the case of Rodolfo, his pages are INSIDE the ISP, which mean all outside requests for his pages still use external bandwidth, so caching pages that reside internal to that ISP save absolutely nothing in bandwidth. Instead, grief is caused to their customer's web pages.
Err, no. You've got it mixed up.
1. I am at home in Guatemala, on Telefonica's network. This is the ISP running a transparent proxy. I am requesting pages from my computer, as a client.
2. The server is in Texas, on EV1's network, at a datacenter. No caching, proxying, or other messing with traffic is taking place.
So yes, my ISP is caching /internal/ requests for /external/ pages, which makes sense. They're just doing it in such an aggressive way as to break some browsing functionality (being able to demand a refresh) and driving me nuts (which is what started this thread).
