As a marginally interesting side note, while "resume" support is part of the
RFC (#2616), it is not required. The RFC refers to the concept as a "partial
GET", where the request message includes a Range header field.

From 14.35.1: "However, not all clients and servers need to support byte-
range operations."

Section 9.3: GET
http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.3

Section 14.35.1: Byte Ranges
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35
