Apache::Session is a persistence framework whose purpose is to provide session management to Web developers. It is designed to work with Apache and mod_perl, but it does not depend on them and will work with any Web server. This module provides a set of classes that give the developer maximum functionality. Session data can be stored in a database, flat files, or shared memory.
The Archive::Zip module allows a Perl program to create, manipulate, read, and write Zip archive files without calling an external program. Members can be added, removed, extracted, replaced, rearranged, and enumerated. They can also be renamed or have their dates, comments, or other attributes queried or modified. Their data can be compressed or uncompressed as needed, and members can be created from members in existing Zip files, or from existing directories, files, or strings.
cgi_buffer is a group of libraries that may be used to improve performance of CGI scripts (and other content generation engines) in some circumstances by applying performance-enhancing HTTP mechanisms that are typically not supported by them. Currently, Perl, Python, and PHP4 are supported. The Python library may also be used as a wrapper around another CGI script.
Finance::Quote is a Perl module which can fetch on-line stock quotes, including those from American, European, Canadian and Australian markets. Information from a number of investment houses is also available. Features include currency lookups and conversions, automatic failover support, and loadable user modules.
FormMagick is a set of Perl modules intended to ease the task of writing multi-page Web forms. It takes a description of the form (fields, validation to perform on each field, etc) in XML format and generates HTML on the fly. Other features include templates for changing the "look and feel" of your forms, and the ability to easily localise your text for other languages.
Perl-LZO (aka Compress::LZO) provides Perl bindings for the LZO data compression library. You can access the LZO library from your Perl scripts thereby compressing ordinary Perl strings. LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed.
