Just been testing a tracert with Sammy, and a thought occurred to me.

If you make a request to a slow and/or remote website with high latency, yet receive a response instantaneously, it might suggest an interception had occurred.

An idea that occurred to me; you could create a simple slow test script server side, set headers to suppress caching, and use AJAX client side to test the response time.

Response time <25ms (where the script time is deliberately restricted to 500ms+) would tell you immediately the request was intercepted (because if it were from a genuine source it would never have returned in less than 500ms).


ISP customers; you don't need Phorm, pure and simple.
Don't be a passive recipient of Phorm cookies.
Until Phorm can be stopped, use the Dephormation Firefox Add On.

RIPA: ISPs HAVE NO CONSENT FOR INTERCEPTION OF THIS TRANSMISSION ;o)
