The cgi-lib.pl library makes CGI scripting in Perl easy enough for anyone to process forms and create dynamic Web content. The library features: Extremely simple to learn and easy to use, Designed for operation under Perl5 and Perl4, Very efficient, Compatibility with all CGI interactions, including File Upload, Convenient utility functions, Compatible with Perl5 security features such as taint, warnings, (command line options -Tw) and use strict, Debugging facilities, Good starting point for migration to more sophisticated libraries, etc.

The HFPM are a set of modules that accept a submitted HTML form, possibly modify the contents of the submitted fields, and output the result using e-mail, appending to a file, and/or displaying it to the user or returning an arbitrary URL. They also operate on the environmental variables passed in from the client and server.

Formdata.pl allows you to test your GETs and POSTs with one script. It's a useful tool in debugging.

Dumpenvs.pl is a simple script that gives you a list of server-supported environment variables and their values. This can be useful for debugging purposes.

This library includes many useful routines: ReadParse which gets all form parameters and writes them into a field variable, PrintHeader which prints the Content-type text/html, HtmlTop(title, background, kopf) that simply prints a head of a HTML document, HtmlBot(title) that prints the bottom of a HTML document, SplitParam that splits a list, CgiError which prints out error messages, Check_Name which checks if a username contains dangerous signs for filenames, Get_Seconds that returns the number of seconds, lock(filehandle) that implements a locking function, unlock(filehandle) that implements a unlocking function, and more.

A cookie is simply a small (up to 20 times 4k per domain) bit of info which servers can store in a browser's client. This script shows an example of how to set and retrieve a cookie.

"HTML 2 PERL" converts any standard HTML file to a list of Perl print statements, either destined for STDOUT, as in cgi output or for printing to a file. It allows you to specify the file handling variable, the input file, and the output file, either via command line or interactively.

A CGI testing harness that allows you to examine the exact output and environment of your CGI programs.

Lingua::Stem takes lists of words an (as determined by the locale) stems them to their root form. This is primarily of use in search applications that need to be able to find conjugated forms of words as well as exact matches.

This is a demonstration script of the 'triple dot cookie' vulnerability in Microsoft Internet Explorer and Netscape. Triple dot cookies can be used to completely by-pass the domain restrictions for cookies in those browsers.

Cookie-lib.pl is a perl library, written in the spirit of cgi-lib.pl to help developers use cookies easily and effectively in web applications.

CfgFile is a class for supporting the loading of a configuration file.

OSUtil is a module to help Perl programs run on mulitple platforms.

mif.pl is a Perl library to parse Frame Maker Interchange Format (MIF). It is designed to be utilized by filters.

formtest.pl is useful for testing forms. It displays the raw url-encoded GET or POST string and parses out the variables for display as html or plain text.

CGI::Minimal provides a lightweight alternative to the CGI.pm module shipped with Perl. It is approximately 1/6th the size of CGI.pm but provides largely compatible access to form decoding and a small number of other tasks essential to writing CGI scripts in Perl. Designed for people who are comfortable working closely with the HTTP protocal and writing HTML directly. Supports file uploading as just another transparently decoded form field.

This is an experimental Perl module that allows you to use lists as the keys for multi-level hashes. Excellent for parse tree generation and other similar tasks where you need to create very deep trees or the tree depth is not known in advance. A real performance win on very deep trees over 'walking the tree' starting from the root node.

Tie::DB_File::SplitHash is designed for support of file size limitted OSes. It transparently splits a DB_File database into as many distinct files as desired. It also distributes hash entries between the files using a randomization algorithm. It has the effect of allowing DB_File hashes to grow to the full size of the partition. Requires 'Digest::SHA1' and 'DB_File' to be installed.

Tie::FileLRUCache provides a persistent filesystem based LRU cache. It uses the 'last accessed' timestamp generated by the file system to determine the 'oldest' cache entry and discards the oldest cache entries when needed to stay under the -keep_last limit. If you store thing very fast (such that many entries receive the _same_ time stamp), it is essentially a coin toss which entry within a single timestamped second gets purged from the cache to make room for new ones.

Class:NamedParms provides key name checking for named accessor parameters. This allows the use of a generic 'get/set' type parameterized accessor while automatically catching accidental mis-spellings and usage of uninitialized parameters. This catches a large class of programming errors without requiring a new accessor for every object parameter.
