net.http: Send entire HTTP request header as one write
When opportunistic writes are enabled this reduces the number of
syscalls and TCP packets sent on the wire.
Experiments with TCP Fast Open made this even more obvious.
That table trick probably wasn't as efficient. Lua generates bytecode
for a table with zero array slots and space for two entries in the hash
part, plus code to set [2] and [4]. I didn't verify but I suspect it
would have had to resize the table when setting [1] and [3], although
probably only once. Concatenating the strings directly in Lua is easier
to read and involves no extra table or function call.

Structure of a session: session { -- properties -- conn -- the tcp connection notopen -- true if stream has not been initiated, removed after receiving <stream:steam> type -- the connection type. Valid values include: -- "c2s_unauthed" - connection has not been authenticated yet -- "c2s" - from a local client to the server username -- the node part of the client's jid (not defined before auth) host -- the host part of the client's jid (not defined before stream initiation) resource -- the resource part of the client's full jid (not defined before resource binding) full_jid -- convenience for the above 3 as string in username@host/resource form (not defined before resource binding) priority -- the resource priority, default: 0 presence -- the last non-directed presence with no type attribute. initially nil. reset to nil on unavailable presence. interested -- true if the resource requested the roster. Interested resources receive roster updates. Initially nil. roster -- the user's roster. Loaded as soon as the resource is bound (session becomes a connected resource). -- methods -- send(x) -- converts x to a string, and writes it to the connection close(x) -- Disconnect the user and clean up the session, best call sessionmanager.destroy_session() instead of this in most cases } if session.full_jid (also session.roster and session.resource) then this is a "connected resource" if session.presence then this is an "available resource" (all available resources are connected resources) if session.interested then this is an "interested resource" (all interested resources are connected resources)
