<h1>JavaScript Includes</h1>
This text is not in the JavaScript include file and could be load-
ed normally by<br>
a bot. However, the text in the next block is contained in a
JavaScript<br>
include file.<br>

The JavaScript include statement includes another file, named
include.js
. You can
see this include statement here:
<script type="text/javascript" src="include.js"></script>
This will cause the file
include.js
to be included as part of the HTML file. How-
ever, the
include.js
file is assumed to be JavaScript, so no
<script>
tags are neces-
sary inside
include.js
. The
include.js
source is shown below:
document.write('This text is coming from a JavaScript include
file<br>');
document.write('It is not contained in the main HTML file, and
must<br>');
document.write('be loaded in a different HTTP GET request.<br>');
As a separate request, the web browser will load the
include.js
file. It is a regular
web document, which can be found at the following address:
http://www.httprecipes.com/1/9/include.js
To process JavaScript includes with a bot, you must examine what they contain and how
you will obtain what you need from them. Like the other JavaScript techniques, it is a matter
of providing the correct HTTP requests to the server and processing the responses. Recipe
9.2 shows how to process this URL.
