This is a bundled distribution of TclHttpd, Tcl, the
Standard Tcl Library, and the Thread extension.

If you already have tcl 8.4 or 8.3 installed, then you can probably
run the Tcl Web Server directly from this distribtuion without
doing any installation steps (The directory will really be
named something like tclhttpd4.0.1) :

cd tclhttpd4.0/bin
tclsh httpd.tcl -port 8001 -debug 1

If you get complaints about missing the Standard Tcl Library,
then you can install just that by running the install.sh script
in the tcllib1.6 directory.

If you want a clean install of everything, including a Tcl 8.4.5
that has thread enabled, then use the Makefile in the top-level directory.
This will compile things under the build directory, segregating
by platform into different subdirectories.

There are a few more README-like files you should read:

blocks.  Without threads, you are forced to put your blocking
operations into CGI scripts so that the external CGI process blocks.
The server continues to service requests until the pipe connected
to the CGI process produces data.

5. Starkit Distribution

The tclhttpd4.0.0.kit file is a starkit that is used with the
tclkit Tcl interpreter.  There is more information about Tclkit at
  http://wiki.tcl.tk/tclkit/
but the basic idea is simple.  All you need is a tclkit binary
installed for your platform, and the platform-independent tclhttpd.kit.
Start the server like this:
  tclkit tclhttpd.kit -port 8001 -docRoot /your/htdocs -library /your/code
If you don't supply a docRoot or library, then you get the sample

Version: 4.0.0
Sat Mar 28 04:44:11 EDT 2015

STARKIT QUICK START

tclkit tclhttpd4.0.0.kit -port 80 -docRoot htmldir -library tcldir

The server loads all the tcl sources in the library.  Try also
tclkit tclhttpd4.0.0.kit -help

STANDARD QUICK START

It requires Tcl 8.6 (or higher) and the Standard Tcl Library.
This uses the cmdline, base64, ncgi, html, sha1, and counter
modules of the Standard Tcl Library. If you must, you
can probably get by with Tcl 8.5 or later if you install
the Standard Tcl Library and the TclOO extension.

The Web server runs under either tclsh or wish.
With wish you get a simple GUI that shows some counters.

For a quick test that runs a server on port 8015, do
UNIX:

1) Test preconditions
	Tcl interpreter: tclsh8.5, tclsh8.6, tclkit (or wish)
        tcllib 1.6 or higher
Try
        tclsh (whatever version)
	package require counter

2) If you can do the above, then you should be able to run the
server directly from this distribution directory without bothering
to configure, make, and install it. e.g., 

	tclsh8.6 bin/httpd.tcl -debug 1
Windows and Macintosh:
	Run wish or tclsh and source bin/httpd.tcl

3) For more detailed installation instructions, see the INSTALL file.

For a complete set of command line options, do
httpd.tcl -help
This lets you set basic parameters like port number and server name.

VERSION SUMMARY

Version 4.0 adds support for Tcl 8.6, and integrates TclOO. The
/lib directory has been moved to /modules, and the layout of modules
now mirrors that of Tcllib. DirectOO adds the ability to implement
dynamic content with TclOO objects. This version adds bootstrap
and markdown support.

Version 3.5 has various bug fixes, improvements to the docs, and
some sample applications.  3.5.1 adds a mail client module.

Version 3.4.3  fixes loading code from the custom code directory,
which broke in 3.4.2

Version 3.4.2 has bug fixes in the directory listing code (dirlist.tcl).
Prevent listing of directory trees outside the URL tree, and get them to work
at all.  Added a fix in upload.tcl so that extra post data is cleaned up
correctly - fixes bugs that occur when GET and POST uploads are mixed.
Minor cleanup to the sample htdocs tree.

Version 3.4.1 fixes CGI POST forms on Windows, a typo in upload.tcl
and the lib/pkgIndex.tcl.  It also disallows the ability to retrieve
.tml, .tclaccess, and .htaccess files.  These simple new APIs crept in:
  Url_AccessInstallPrepend, Url_AccessUnInstall
  Mtype_Add, Mtype_Reset
  Direct_UrlRemove

Version 3.4 has several updates to the Doc, Upload, and Thread modules
done by Melissa Chawla of Panasas. Please see the ChangeLog for details.
There is also a small modification to support If-Modified-Since optimization
in Httpd_ReturnFile contributed by Brian Meagher.  Don Porter contributed
virtual host support, so you can support several sites with one server.
Please see README.virthost for details

Version 3.3.1 was just a cleanup of the installation files and
configure scripts. (acruz)

Version 3.3 fixes more bugs in CGI handling and
adds a simple file upload domain handler.

Version 3.2.1 fixes bugs in CGI handling related to the changes
in 3.2 in the way POST data is handled.  

Version 3.2 changes the way you customize a TclHttpd installation with
the goal of not having to modify the bin/httpd.tcl and bin/httpdthread.tcl
scripts, although in some cases this will still be necessary.  A new
"custom code" directory is supported and the server will load all the
code from that directory during startup.  Specify this with the -library
command line option or the "library" Config specification in your .rc file.

Version 3.1.0 renames all the packages to be httpd::foo instead of just
foo, so that the package namespace is a bit more organized when TclHttpd
is installed along with the rest of Tcl and Tk.  Other that that,
it is essentially identical with 3.0.4.

Version 3.0.4 fixes yet-another bug with Doc_AddRoot.

Version 3.0.3 fixes another bug with Doc_AddRoot, and fixes the
bundled distribution so you can use the Thread extension again.

Version 3.0.2 fixes a serious SECURITY BUG that let 3.0.0 and 3.0.1 
serve up any old file on your system.  That bug was not present in earlier
versions of the server.

Version 3.0.1 has minor bug fixes and (hopefully) some improvements
in the bundled distribution.

Version 3.0.0 has three major changes:
* Use of Standard Tcl Library modules.  The server looks around for the
tcllib distribution and automatically uses it.  One goal of this conversion
is to eliminate the use of the page global array and replace that with
calls to the ncgi module.
* Support for threads.  If you configure and build Tclsh with --enable-threads
and you have the Thread extension available, the the server can 
use threads to service requests.
* Support for SSL.  If you have the "tls" extension installed, then you can
start an SSL server by giving the -https_port command line argument.

Version 2.3.6 is the last in the 2.3 series.  It has a few minor
bug fixes.  The next release, 3.0, will support threading using
the Thread extension and SSL using the TLS extension.

Version 2.3 changes the way post data is  handled.
The various point releases (e.g., 2.3.4) fix important
bugs in cookie handling and the new post data handler.

Version 2.1.6 introduces a configuration file, tclhttpd.rc
You can edit this to tune the set of modules used by the server,
or to hardwire the port, etc.

If you have Scotty installed, then you can try out the SNMP demo.
You'll need to arrange to have the Tnm*.so library on the
auto_path for your shell.  I have found that 2.1.5 works
with 8.0a2, but not with 8.0b1 because Tcl_GetFile has gone.

MAILING LISTS

There is a mailing list for users of the Tcl web server at
SourceForge as part of the tclhttpd project.  Please sign

WWW

The current URL for the distribution can be found in
http://core.tcl.tk/tclhttpd

This site contains the fossil source repository, as well as the
most up to date documentation.

Current version is 4.0.0
This is reflected in the following files (sigh)

README
        For informational purposes
configure.in
        The patchlevel is either "" or ".1" etc.
        *re-run* autoconf to update configure
bin/httpd.tcl
        set v 4.0.0
        So it can look for the right tclhttpd library
lib/version.tcl
        To set the right version string.  This does
        package provide major.minor only, but the string
        has the date and patchlevel.  The actual value
        of the httpd::version package number isn't used.
lib/pkgIndex.tcl

What's new in TclHttpd

4.0
This version targets the new TclOO features backed into 8.6, as
well as utilizing sqlite as a database backend.

3.5

Mostly this is a cleanup of the code and web pages to cleanly
separate out the core server from various sample applications and
demo code.  The default web site is defined by the htdocs and custom
subdirectories, and all the other stuff is organized under sampleapp.
There are some new security controls over the debug URL so you can

#

# and checked with opt-val and opt-bool. The format of options-spec follows.
#
# A boolean option is of the form:
#
## name[=0|1]  => "Description of this boolean option"
#
# The default is name=0, meaning that the option is disabled by default.
# If name=1 is used to make the option enabled by default, the description should reflect
# that with text like "Disable support for ...".
#
# An argument option (one which takes a parameter) is of the form:
#
## name:[=]value  => "Description of this option"
#
# If the name:value form is used, the value must be provided with the option (as --name=myvalue).
# If the name:=value form is used, the value is optional and the given value is used as the default
# if is not provided.
#
# Undocumented options are also supported by omitting the "=> description.
# These options are not displayed with --help and can be useful for internal options or as aliases.
#
# For example, --disable-lfs is an alias for --disable=largefile:
#
## lfs=1 largefile=1 => "Disable large file support"
