In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print
<p>john</p> <p>steve</p> <p>mike</p>with custom tag <my:foreach> :
<my:foreach var="who" value="john steve mike"> ...These are the files: pom.xml

The -d switch for cURL sends HTTP POST with data from the command line. To verify the data being posted, this is a CGI script that echos the data back:

cURL is a command line tool for transferring files with URL syntax. The main purpose and use for cURL is to automate unattended file transfers or sequences of operations. It's really easy to see HTTP headers with curl:
C:\>curl --head http://www.google.com HTTP/1.0 ...or, headers and page together (dump headers to stdout):
$ curl --dump-header - http://www.google.com HTTP/...Download openssl from openssl.org:

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf :
LoadModule python_module modules/mod_python.so ...Python script:
import time, os from os.path import basename ...
