for this topic supports the latest PTF levels for HTTP Server for i5/OS .
|
||
|

It is recommended that you install the latest PTFs to upgrade to the latest
|
||
|
|
level of the HTTP Server for i5/OS. Some of the topics documented here are
|
||
|
|
not available prior to this update. See <a href="http://www-03.ibm.com/servers/eserver/iseries/software/http/services/service.html" target="_blank">http://www.ibm.com/servers/eserver/iseries/software/http/services/service.htm</a> <img src="www.gif" alt="Link outside Information Center" /> for more information. </div>
|
||
|
|
<p>Web spiders, Web crawlers, and robots are programs that traverse the Internet
|
||
|
|
retrieving documents and following links in those documents. You may have
|
||
|
|
noticed entries in your log files that document requests for /robots.txt files
|
||
|
|
or requests for many of your Web documents. These requests may be from a robot.
|
||
|
|
Most robots adhere to the robot exclusion protocol. If you want to control
|
||
|
|
what portion of your Web site robots attempt to visit, you can either use
|
||
|
|
a robots.txt file or the robots meta tag. </p>
|
||
|
|
<p><strong>The robots.txt file </strong> </p>
|
||
|
|
<p>The robots.txt file must be placed in the document root directory of the
|
||
|
|
server. The following is an example of a robots.txt file: </p>
|
||
|
|
<pre class="block">User-agent: *
|
||
|
|
Disallow: /cgi-bin/</pre>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Make sure that you do not alert hackers to important directories or
|
||
|
|
files by listing them in the robots.txt file. </div>
|
||
|
|
<p><strong>Robots meta tag </strong></p>
|
||
|
|
<p>The robots meta tag can be placed in HTML documents to tell the robot: </p>
|
||
|
|
<ul><li>Do not index a document <pre><META NAME="ROBOTS" CONTENT="NOINDEX"></pre>
|
||
|
|
</li>
|
||
|
|
<li>Do not follow links in a document <pre><META NAME="ROBOTS" CONTENT="NOFOLLOW"></pre>
|
||
|
