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.
