Perl is a high-level, general-purpose programming language that makes easy things easy and hard things possible. It is optimized for scanning arbitrary text files and system administration. It has built-in extended regular expression matching and replacement, a dataflow mechanism to improve security with setuid scripts and is extensible via modules that can interface to C libraries.
Apache::ASP provides an Active Server Pages port to the Apache Web Server with Perl as the host scripting language. Apache::ASP allows a developer to create dynamic Web applications with session management and embedded Perl code. There are also many powerful extensions, including XML taglibs, XSLT rendering, and new events not originally part of the ASP API.
ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but it uses C++ as a core implementation language. It implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml, and more. Flexible allocator/garbage collection, threading, and Unicode are implemented in the core of ACDK. Extensions make C++ objects available for reflection, serialization, aspect-oriented class attributes, and [D]ynamic [M] ethod [I]nvocation. This DMI acts as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, and VBScript) and standard component technologies (CORBA and COM).
SpeedyCGI (aka PersistentPerl) is a way to run Perl scripts persistently, which usually makes them run much more quickly. Converting scripts to use SpeedyCGI is in most cases as simple has changing the interpreter line at the top of the script. After the script is initially run, instead of exiting, SpeedyCGI keeps the Perl interpreter running in memory. During subsequent runs, this interpreter is used to handle new requests, instead of starting a new Perl interpreter for each execution.
