So to be clear, a L1 (elite) proxy doesn't show your IP anywhere and also doesn't have any other proxy indicaters like HTTP_VIA.. A L2 doesn't show your IP but may indicate it's a proxy.. L3 uses a different IP but you can see your IP in there and/or that it's a proxy. So when trying out Charon, one of the things I notice it uses to flag a "VIA", which would differentiate between L1 or L2, is the HTTP_CONNECTION header... Thing is, that header is there regardless of whether or not you're using a proxy. So should the ini file be changed to remove that from the VIA flagging for Charon to get a clearer indication (and score) of L1/L2? The other thing is that in the past I've seen the header X_BLUECOAT_VIA around that actually indicates a proxy from a particular vendor. I've read things where some sites block that as part of their process to try and block out proxy access... So should that be added into the Charon settings for VIA? Different question.. When Scrapebox checks that a proxy passes the "google" test, is it just testing that it can in fact access google for a query and that's it? I thought I saw that option in Charon as well, or maybe it was a site check thing that can be set up.
