Why not use c_str()? data() doesn't guarantee null-terminated string and WebData
expects that according to its signature.

Hm I don't see how WebData can expect that, when it also takes a size parameter?
Seems to be expecting just raw bytes (and the implementation just creates a
SharedBuffer with the same parameters).
