nit: "WebSocketClient implementation." ?

[Takashi Toyoshima, 2011/11/24 03:55:49]

Done.

+  // TODO(toyoshim): Check if OVERRIDE is needed for following methods.

[Takashi Toyoshima, 2011/11/24 03:55:49]

Oh, I forget to remove this TODO.
I think following virtual functions need OVERRIDE, right?

[dmichael (off chromium), 2011/11/24 04:32:36]

Since they're overriding WebKit functions it's optional, but preferred to leave
them if you don't expect to change the WebKit API in the near future.
