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.
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.
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.
serverizor allows you to take a normal command- based program, and run it as a tcp server in the background. This means that you can start up such programs once, and then connect to them with a command-line client, and run commands, disconnect, connect again from some other machine, etc. So, you can use it to boot up a large program such as emacs or lisp (in interpretor mode, not in editor/windowing mode) in the background, and then whenever you want to run emacs/lispy scripts, you could just run a serverizor client with a few commands. Therefore, the client and the server are the same program.
