This is a technical violation of most of the RFCs.  Most protocols
specify the "\r\n" combination as the line delimiter for network
traffic.  Requiring a NUL afterwards or instead of this delimiter makes
this type of string handling unsuitable for most network applications.

Since Flash is certainly able to deal with HTTP requests and responses
(which don't embed NULs after every line), it makes me think that this
NUL is not a requirement, but that there is a different method for
network applications.  You might want to look into that.
