should this be net::HttpRequestHeaders?

[kinuko, 2013/12/20 10:12:42]

This struct's going to be sent over IPC, while HttpRequestHeaders looks too rich
(non-PODS)

can you move the ctor/dtor before the members.

can you add parameters to the ctor to initialize the fields (so it's not
possible to create the struct without initializing it)

[kinuko, 2013/12/20 10:12:42]

Done.
Done, but also left empty ctor since it's required to make the IPC code work.
