Came across this today: Nokia Admits Decrypting User Data But Denies Man-in-the-Middle Attacks http://www.techweekeurope.co.uk/new...e-middle-attacks-103799?ModPagespeed=noscript which also suggests that Opera Mini does a MITM of HTTPS connections. Elsewhere I saw contradictory information about whether Amazon Silk does this as well. Then stumbled across these: http://www.igvita.com/2012/06/25/spdy-and-secure-proxy-support-in-google-chrome/ http://www.igvita.com/2011/12/01/web-vpn-secure-proxies-with-spdy-chrome/ which suggest Amazon Silk doesn't route the *HTTPS* traffic through their SPDY proxy. This is my first introduction to SPDY proxies and I find the scenario of tunneling SSL over an SSL connection to a SPDY proxy interesting. I think this passes target hostname/port to said proxy which may or may not be acceptable based on the situation. Anyway, thought I'd post some of this as an FYI and reminder to check how browsers/devices actually operate.
