+A persistent connection allows multiple HTTP/1.1 transactions to be
+carried over the same TCP connection.  Pipelining allows a
+client to make multiple requests over a persistent connection without
+waiting for each response.  The server sends responses in the same order
+that the requests were received.
+.PP
+If a POST request fails to complete, typically user confirmation is
+needed before sending the request again.  The user may wish to verify
+whether the server was modified by the failed POST request, before
+sending the same request again.
+.PP
+A HTTP request will use a persistent socket if the call to
+\fBhttp::geturl\fR has the option \fB-keepalive true\fR. It will use
+pipelining where permitted if the \fBhttp::config\fR option
+\fB-pipeline\fR is boolean \fBtrue\fR (its default value).
+.PP
+The http package maintains no more than one persistent connection to each
+server (i.e. each value of
+.QW "domain:port" ).
+If \fBhttp::geturl\fR is called to make a request over a persistent
+connection while the connection is busy with another request, the new
+request will be held in a queue until the connection is free.
+.PP
+The http package does not support HTTP/1.0 persistent connections
+controlled by the \fBKeep-Alive\fR header.
+.SS "SPECIAL CASES"
+.PP
+This subsection discusses issues related to closure of the
+persistent connection by the server, automatic retry of failed requests,
+the special treatment necessary for POST requests, and the options for
+dealing with these cases.
+.PP
+In accordance with RFC 7230, \fBhttp::geturl\fR does not pipeline
+requests that use the POST method.  If a POST uses a persistent
+connection and is not the first request on that connection,
+\fBhttp::geturl\fR waits until it has received the response for the previous
+request; or (if \fBhttp::config\fR option \fB-postfresh\fR is boolean \fBtrue\fR) it
+uses a new connection for each POST.
+.PP
+If the server is processing a number of pipelined requests, and sends a
+response header
+.QW "\fBConnection: close\fR"
+with one of the responses (other than the last), then subsequent responses
+are unfulfilled. \fBhttp::geturl\fR will send the unfulfilled requests again
+over a new connection.
+.PP
+A difficulty arises when a HTTP client sends a request over a persistent
+connection that has been idle for a while.  The HTTP server may
+half-close an apparently idle connection while the client is sending a
+request, but before the request arrives at the server: in this case (an
+.QW "asynchronous close event" )
+the request will fail.  The difficulty arises because the client cannot
+be certain whether the POST modified the state of the server.  For HEAD or
+GET requests, \fBhttp::geturl\fR opens another connection and retransmits
+the failed request. However, if the request was a POST, RFC 7230 forbids
+automatic retry by default, suggesting either user confirmation, or
+confirmation by user-agent software that has semantic understanding of
+the application.  The \fBhttp::config\fR option \fB-repost\fR allows for
+either possibility.
+.PP
+Asynchronous close events can occur only in a short interval of time.  The
+\fBhttp\fR package monitors each persistent connection for closure by the
+server.  Upon detection, the connection is also closed at the client end,
+and subsequent requests will use a fresh connection.
+.PP
+If the \fBhttp::geturl\fR command is called with option \fB-keepalive true\fR,
+then it will both try to use an existing persistent connection
+(if one is available), and it will send the server a
+.QW "\fBConnection: keep-alive\fR"
+request header asking to keep the connection open for future requests.
+.PP
+The \fBhttp::config\fR options \fB-pipeline\fR, \fB-postfresh\fR, and
+\fB-repost\fR relate to persistent connections.
+.PP
+Option \fB-pipeline\fR, if boolean \fBtrue\fR, will pipeline GET and HEAD requests
+made
+over a persistent connection.  POST requests will not be pipelined - if the
+POST is not the first transaction on the connection, its request will not
+be sent until the previous response has finished.  GET and HEAD requests
+made after a POST will not be sent until the POST response has been
+delivered, and will not be sent if the POST fails.
+.PP
+Option \fB-postfresh\fR, if boolean \fBtrue\fR, will override the \fBhttp::geturl\fR option
+\fB-keepalive\fR, and always open a fresh connection for a POST request.
+.PP
+Option \fB-repost\fR, if \fBtrue\fR, permits automatic retry of a POST request
+that fails because it uses a persistent connection that the server has
+half-closed (an
+.QW "asynchronous close event" ).
+Subsequent GET and HEAD requests in a failed pipeline will also be retried.
+\fIThe -repost option should be used only if the application understands
+that the retry is appropriate\fR - specifically, the application must know
+that if the failed POST successfully modified the state of the server, a repeat POST
+would have no adverse effect.

+# ------------------------------------------------------------------------------
+# These tests are a bit awkward because the main test kit analyses whether all
+# requests are satisfied, with retries if necessary, and it has result analysis
+# for processing retry logs.
+# - *.18*-testEof tests that certain requests are NOT satisfied, so the analysis
+#   is a one-off.
+# - Tests *.18a-testEof depend on client/server timing - the test needs to call
+#   http::geturl for all requests before the POST (request 2) is cancelled.
+#   We test that requests 2, 3, 4 are all cancelled.
+# - Other tests *.18*-testEof may not request 3 and 4 in time for the to be
+#   added to the write queue before request 2 is completed. We simply check that
+#   request 2 is cancelled.
+# - The behaviour is different if all connections are allowed to time out
+#   (label "j").  This case is not needed to test -repost 0, and is omitted.
+# - Tests *.18*-normal and *.19* are conventional (-repost 0 should have no
+#   effect).

+# "Package" httpTestScript for executing test scripts written in a convenient
+# shorthand.
+# ------------------------------------------------------------------------------
+
+# ------------------------------------------------------------------------------
+# Documentation for "package" httpTestScript.
+# ------------------------------------------------------------------------------
+# To use the package:
+# (a) define URLs as the values of elements in the array ::httpTestScript
+# (b) define a script in terms of the commands
+#         START STOP DELAY KEEPALIVE WAIT PIPELINE GET HEAD POST
+#     referring to URLs by the name of the corresponding array element.  The
+#     script can include any other Tcl commands, and evaluates in the
+#     httpTestScript namespace.
+# (c) Use the command httpTestScript::runHttpTestScript to evaluate the script.
+# (d) For tcltest tests, wrap the runHttpTestScript call in a suitable "test"
+#     command.
+# ------------------------------------------------------------------------------
+# START
+# Must be the first command of the script.
+#
+# STOP
+# Must be present in the script to avoid waiting for client timeout.
+# Usually the last command, but can be elsewhere to end a script prematurely.
+# Subsequent httpTestScript commands will have no effect.
+#
+# DELAY ms
+# If there are no WAIT commands, this sets the delay in ms between subsequent
+# calls to http::geturl.  Default 500ms.
+#
+# KEEPALIVE
+# Set the value passed to http::geturl for the -keepalive option.  The command
+# applies to subsequent requests in the script. Default 1.
+#
+# WAIT ms
+# Pause for a time in ms before sending subsequent requests.
+#
+# PIPELINE boolean
+# Set the value of -pipeline using http::config.  The last PIPELINE command
+# in the script applies to every request. Default 1.
+#
+# POSTFRESH boolean
+# Set the value of -postfresh using http::config.  The last POSTFRESH command
+# in the script applies to every request. Default 0.
+#
+# REPOST boolean
+# Set the value of -repost using http::config.  The last REPOST command
+# in the script applies to every request. Default 1 for httpTestScript.
+# (Default value in http is 0).

+# args    - strings that will be joined by "&" and appended to the query
