You shouldn't need both a data_reduction_proxy_enabled_ and a
spdy_proxy_auth_enabled_. 

[megjablon, 2014/07/16 23:07:14]

This is how we fixed the problem of it being initialized twice. Will
data_reduction_proxy_enabled_ be safe to use?

[bengr, 2014/07/16 23:28:14]

Figure out the initialization order and the order of use. If one is initialized
and used before the other, use that one only. If not, pick a single
initialization site that guarantees initial use is post initialization.
