+.SS "PURPOSE"
+.PP
+Command \fB::http::geturl\fR uses the Tcl \fB::socket\fR command with
+the \fI\-async\fR option to connect to a remote server, but the return from
+this command can be delayed in adverse cases (e.g. a slow DNS lookup),
+preventing the event loop from processing other events.
+This delay is avoided if the \fB::socket\fR command is evaluated in another
+thread.  The Thread package is not part of Tcl but is provided in
+"Batteries Included" distributions.  Instead of the \fB::socket\fR command,
+the http package uses \fB::http::socket\fR which makes connections in the
+manner specified by the value of \fI\-threadlevel\fR and the availability
+of package Thread.
+.PP
+.SS "WITH TLS (HTTPS)"
+.PP
+The same \fI\-threadlevel\fR configuration applies to both HTTP and HTTPS
+connections.
+HTTPS is enabled by using the \fBhttp::register\fR command, typically by
+specifying the \fB::tls::socket\fR command of the tls package to handle TLS
+cryptography.  The \fB::tls::socket\fR command connects to the remote server by
+using the command specified by the value of variable \fB::tls::socketCmd\fR, and
+this value defaults to "::socket".  If http::geturl finds
+that \fB::tls::socketCmd\fR has this value, it replaces it with the value
+"::http::socket".  If \fB::tls::socketCmd\fR has a value other than "::socket",
+i.e. if the script or the Tcl installation has replaced the value "::socket"
+with the name of a different command, then http does not change the value.
+The script or installation that modified \fB::tls::socketCmd\fR is responsible
+for integrating \fR::http::socket\fR into its own replacement command.
+.PP
+.SS "WITH A CHILD INTERPRETER"
+.PP
+The peer thread can transfer the socket only to the main interpreter of the
+script's thread.  Therefore the thread-based \fB::http::socket\fR works with
+non-zero \fI\-threadlevel\fR values only if the script runs in the main
+interpreter.  A child interpreter must use \fI\-threadlevel 0\fR unless the
+parent interpreter has provided alternative facilities.  The main parent
+interpreter may grant full \fI\-threadlevel\fR facilities to a child
+interpreter, for example by aliasing, to \fB::http::socket\fR in the child,
+a command that runs \fBhttp::socket\fR in the parent, and then transfers
+the socket to the child.

+# ------------------------------------------------------------------------------
+# This command is a drop-in replacement for ::socket.
+# Arguments and return value as for ::socket.
+#
+# Notes.
+# - http::socket is specified in place of ::socket by the definition of urlTypes
+#   in the namespace header of this file (http.tcl).
+# - The command makes a simple call to ::socket unless the user has called
+#   http::config to change the value of -threadlevel from the default value 0.
+# - For -threadlevel 1 or 2, if the Thread package is available, the command
+#   waits in the event loop while the socket is opened in another thread.  This
+#   is a workaround for bug [824251] - it prevents http::geturl from blocking
+#   the event loop if the DNS lookup or server connection is slow.
+# - FIXME Use a thread pool if connections are very frequent.
+# - FIXME The peer thread can transfer the socket only to the main interpreter
+#   in the present thread.  Therefore this code works only if this script runs
+#   in the main interpreter.  In a child interpreter, the parent must alias a
+#   command to ::http::socket in the child, run http::socket in the parent,
+#   and then transfer the socket to the child.
+# - The http::socket command is simple, and can easily be replaced with an
+#   alternative command that uses a different technique to open a socket while
+#   entering the event loop.
+# - Unexpected behaviour by thread::send -async (Thread 2.8.6).
+#   An error in thread::send -async causes return of just the error message
+#   (not the expected 3 elements), and raises a bgerror in the main thread.
+#   Hence wrap the command with catch as a precaution.
