 appendix A -- Web Resources appendix A Web Resources
CONTENTS
As mentioned in previous chapters, one of the greatest things about programming with CGI is the vast number of resources available to help you. Everything from tutorials to prewritten programs is available on the Web. I have spent many hours compiling a list of as many of these CGI resources as I could find, and it is included here for you. I have purposely tried to leave out any site that just sells CGI products or does Web consulting, because it would not be fair to have some but not all of the companies that do so. I have included companies that produce freeware or shareware products related to CGI. O'Reilly and Associates CGI Information Page http://www.ora.com/info/cgi O'Reilly is the distributor of WebSite server software, and because of this, this page contains a lot of WinCGI-related code snippets, samples, and so on. Dale Bewley's PD Perl Site http://www.engr.iupui.edu/~dbewley/perl/ Contains public domain Perl scripts that do a variety of tasks. EIT Software Archive http://www.eit.com/goodies/software/ Home of hypermail, libcgi, and so on. Although the software is still there, most of it is no longer supported by EIT. The CGI Collection http://www.selah.net/cgi.html This is a collection of CGI information, links to other CGI sites, and CGI scripts written in various languages. The scripts here cover a lot of the things that CGI is generally used for (mail form handling, clocks, counters, and so on). Intro to CGI Programming at the University of Utah http://ute.usi.utah.edu/bin/cgi-programming/counter.pl/cgi-programming/index.html This site contains a tutorial that introduces people to the basics of CGI programming. It goes over topics such as form handling, security, debugging, and so on. Sample programs are also included. Languages used are the Bourne shell and Perl. Sundqvist's Web Developers Bookmarks http://www.abo.fi/~csundqvi/cgi.htm A list of links to other pages of CGI links, various overviews of CGI, various documentation on CGI, and various pages containing programs written in CGI. Mooncrow's CGI/Perl Source Page http://www.seds.org/~smiley/cgiperl/cgi.htm A page containing links to docs on general CGI programming and links to specific programs/info on Perl CGI programming. Jobs for CGI Programmers http://WWW.Stars.com/Jobs/ A place where people who need CGI/Web programmers can post their needs, so that the people who need jobs can contact them. Lincoln D. Stein's CGI Examples http://www-genome.wi.mit.edu/WWW/examples/Ch9/ This page contains sample scripts from a book on how to set up and run a Web site. A CGI Programmer's Reference http://www.best.com/~hedlund/cgi-faq/ These pages are intended to collect information useful to Common Gateway Interface (CGI) programmers. ACGI C++ Class Hierarchy http://www.serve.com/adc/achat/acgi.html This is a link to a C++ class hierarchy that provides a very complete way to write CGI apps in C++. It is the most full featured C++ class hierarchy I know of. C++ CGI Class ftp://www.math.unh.edu/pub/black/cgiClass A class to aid development of CGI scripts written in C++. The class includes methods for HTML formatting as well as handling forms. CGI Form Handling in Perl http://www.bio.cam.ac.uk/web/form.html Perl is an excellent language for a variety of tasks, especially those that require text management and data parsing. As a result, it is well suited for writing code to manage the common gateway interface (CGI) forms that have become the mainstay of World Wide Web interactive communication via HTML. CGI Test Cases http://hoohoo.ncsa.uiuc.edu/cgi/examples.html This document references a test server that has implemented the CGI interface. It is provided to give a better understanding of how CGI works in reality. If you are interested, you should look at the source for the CGI script used in these examples. CGI Specification http://www.ast.cam.ac.uk/%7Edrtr/cgi-spec.html The Common Gateway Interface, or CGI, is an interface for running external programs, or gateways, under an information server. Currently, the supported information servers are HTTP servers. CGI.pm-a Perl5 CGI Library http://www-genome.wi.mit.edu/ftp/pub/software/WWW/ This Perl 5 library uses objects to create Web fill-out forms on-the-fly and parse their contents. It is similar to cgi-lib.pl in some respects. It provides a simple interface for parsing and interpreting query strings passed to CGI scripts. CGI/1.1 Script Support of the CERN Server http://www.w3.org/hypertext/WWW/Daemon/User/CGI/Overview.html Server scripts are used to handle searches, clickable images, and forms, and to produce synthesized documents on-the-fly. See calendar and finger gateway for examples. CGIHTML-C Library for CGI http://hcs.harvard.edu/~eekim/web/cgihtml/ Describes a set of C routines for easily writing CGI programs. Includes documentation, a brief tutorial, and sample programs. CGILIB 3.0 http://phonos.upf.es/~jordinas/esp/cgi.htm This is a CGI library. The code compiles in Windows NT and Posix systems. CGIwrap-More Secure User Access to CGI Scripts http://wwwcgi.umr.edu/~cgiwrap CGIwrap allows system administrators to let users create their own CGI scripts. CGIwrap performs various security checks on the scripts before changing the ID to match the owner of the script.

EIT's CGI Library http://wsk.eit.com/wsk/dist/doc/libcgi/libcgi.html These functions help you write virtual document (CGI) programs using C. Look at the template.c file for an illustrative example. Feel free to download the latest distributions from ftp.eit.com.

John Donohue's Perl CGI Examples http://www.panix.com/~wizjd/test.html Some examples of CGI programming written in Perl, such as an image map without using imagemap.c, juggling variables (maintaining state information) between pages, generating a random number, searching for names in a phone book, and a simple self-scoring questionnaire. Matt's Script Archive http://worldwidemart.com/scripts/ This site consists of many free CGI scripts for the taking. They can help you learn how to build your own CGI programs, or you can use them as is and install them on your system. Examples of the scripts include a guestbook, a free-for-all link page, a bulletin board message system, a form to e-mail gateway, a random image displayer, a random link generator, a countdown, and many more. NR Gateways http://www.nr.no/demo/gateways.html This gives pointers to gateways and Plexus utilities developed at Norsk Regnesentral. Selena Sol's Public Domain CGI Script Library http://www.eff.org/~erict/Scripts/ Public domain CGI scripts written by Selena Sol (shopping carts, feedback forms, groupware calendar, counters, clocks, animation, bulletin boards, and miscellaneous applications). Setting up CGI in ncSA httpd http://hoohoo.ncsa.uiuc.edu/docs/tutorials/cgi.html This is the original tutorial on how to create CGI applications. Although it is old, it covers a lot of CGI concepts. The Common Gateway Interface http://hoohoo.ncsa.uiuc.edu/cgi/primer.html This document is intended to ease you into the idea of writing your own CGI programs with simplified examples and an explanation that is less technically oriented than the interface specification itself. The Common Gateway Interface Specification http://hoohoo.ncsa.uiuc.edu/cgi/interface.html This is the original CGI 1.0 specification. UnCGI Version 1.3 http://www.hyperion.com/~koreth/uncgi.html This is uncgi, a front end for processing queries and forms from the Web on UNIX systems. You can get it via anonymous FTP from ftp.hyperion.com or depending on your browser, by following this link. Without this program, if you wanted to process a form, you'd have to either write or dig up routines to translate the values of the form's fields from URL encoding to whatever your program required.

The only other non-HTTP based online resource I have found to be useful and available to people with accounts on either AOL, CompuServe, or MSN is the Usenet group comp.infosystems.www.authoring.cgi. A mailing list for CGI programming does exist, but traffic on it was nonexistent for the six months I was a member. There is currently no existing centralized FTP site for CGI resources. The resources available on AOL, CompuServe, and MSN are easily found and centralized, so there is no reason to list them here.
