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.

The NoMachine NX Web Companion is a small Java applet and a plugin interface that links the availability of the Web to the unmatched power of NX.

NoMachine NX is a fast terminal server system based on the X11 protocol. In addition, NX also translates and embeds the MS Windows Terminal Server and VNC protocols into X/NX. NX is an order of magnitude faster than VNC or X11 and can run on bandwidth as narrow as 10 kBit/sec.

By embedding RDP and RFB, it enables users to compress and accelerate remote Windows and VNC sessions. NX lets you work fluently even across slow links like modems.

The NX project provides a suite of libraries and X11 proxying agents implementing efficient compression and optimized transport of X11, SMB, IPP, HTTP, and arbitrary protocols like audio over the Internet.

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;
