Web Perl module contains a set of useful routines for many webworking purposes.

This module was primarily made for UNIX/Linux-Systems. Parts of it cannot be used on other systems. E.g. the procedures for file locking demand systems that can use symlinks. If you use the modul on systems where symlinks cannot be used, fatal errors may happen.

ABSTRACT

This perl module serves users with several useful routines for many purposes, like generating webpages, processing CGI scripts, working with XML datafiles and net-connections. It also uses own variants of routines, that was invented first in the famous libraries CGI.pm and cgi-lib.pl.

INSTALLATION

If you dont have sufficient privileges to install web.pm in the Perl library directory, you can put web.pm into some convenient spot, such as your home directory, or in cgi-bin itself and prefix all Perl scripts that call it with something along the lines of the following preamble:

use lib /home/myname/perl/lib;
use web;

NLock

This routine allows to set a filelock across NFS-boundaries. The common used perl-routine flock() fails at this point, so this routine is a useable alternative for bigger file-systems. It uses the modular functions link() and unlink() to mark a file locked. In addition to this, it also gives the locked file a counter: A file that is locked for more than $web::MAX_LOCKTIME seconds will be freed by the next process that calls NLock() on this file. A calling process gets either 0 or 1 as a return value, where 1 is returned if the file-locking was successful. 0 is returned only if the process waits for more than $web::MAX_WAITLOCK seconds or if symlink() fails.

Example 1:

$filename = "data.txt";
NLock($filename);
open(f1,"$filename");
# do something
close f1;
NUnlock($filename);

Example 2:

#!/local/bin/perl5
use web;

$stat= &NLock("jump.pl");
print "Lock: stat= $statn";
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
sleep 8;
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
$stat= &NUnlock("jump.pl");
print "Unlock: stat= $statn";
exit;

Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.).
When I began using my cell phones mobile web browser, one of the things I realized was that there were a lot of web pages that my cell phones web browser simply wouldnt let me see. My shiny new Motorola Razr from T-Mobile, for many pages, would display an error message like "413: Page cannot be displayed." It happened annoyingly often; browsing the web from my cell phone was a lot like trying to read a book or a magazine with large chunks simply ripped out. And when I tried troubleshooting, I might have missed something, but it seemed like a big problem without an easily available solution.
So I tried to provide my own solution. I made a proxy that would present webpages for the mobile web so that they would display in a way that would work for my cell phones web browser. Technologies include paging, tag cleaning, and optional caching to improve performance, but without getting into technical details, this means that I can access some pages on the web that I couldnt access earlier.
Enhancements:
- A bug that caused the script to spuriously report 404 errors was fixed.
- A smaller default page size was set so that tag-rich pages would be rendered in a way more likely to be displayable on mobile Web browsers.

Audio::DB::Web is a Perl module that assists in web-based queries of an MP3 Database.

SYNOPSIS

use Audio::DB::Web;
my $mp3->

Audio::DB is a module for creating relational databases of MP3 files directly from data stored in ID3 tags. Once created, Audio::DB provides various methods for creating reports and web pages of your collection. Although its nutritious and delicious on its own, Audio::DB was created for use with Apache::Audio::DB, a subclass of Apache::MP3. This module makes it easy to make your collection web-accessible, complete with browsing, searching, streaming, multiple users, playlists, ratings, and more!

Web Bench is very simple tool for benchmarking WWW or proxy servers. Uses fork() for simulating multiple clients and can use HTTP/0.9-HTTP/1.1 requests.
This benchmark is not very realistic, but it can test if your HTTPD can realy handle that many clients at once (try to run some CGIs) without taking your machine down.
Displays pages/min and bytes/sec. Can be used in more aggressive mode with -f switch.
Enhancements:
- allow building with both Gnu and BSD make
