URI.Munge
|
|
TYPE: string/null
|
|
VERSION: 1.3.0
|
|
DEFAULT: NULL
|
|
--DESCRIPTION--
|
|
|
|
<p>
|
|
Munges all browsable (usually http, https and ftp)
|
|
absolute URIs into another URI, usually a URI redirection service.
|
|
This directive accepts a URI, formatted with a <code>%s</code> where
|
|
the url-encoded original URI should be inserted (sample:
|
|
<code>http://www.google.com/url?q=%s</code>).
|
|
</p>
|
|
<p>
|
|
Uses for this directive:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Prevent PageRank leaks, while being fairly transparent
|
|
to users (you may also want to add some client side JavaScript to
|
|
override the text in the statusbar). <strong>Notice</strong>:
|
|
Many security experts believe that this form of protection does not deter spam-bots.
|
|
</li>
|
|
<li>
|
|
Redirect users to a splash page telling them they are leaving your
|
|
website. While this is poor usability practice, it is often mandated
|
|
in corporate environments.
|
|
</li>
|
|
</ul>
|
|
<p>
|
|
Prior to HTML Purifier 3.1.1, this directive also enabled the munging
|
|
of browsable external resources, which could break things if your redirection
|
|
script was a splash page or used <code>meta</code> tags. To revert to
|
|
previous behavior, please use %URI.MungeResources.
|
|
</p>
|
|
<p>
|
|
You may want to also use %URI.MungeSecretKey along with this directive
|
|
in order to enforce what URIs your redirector script allows. Open
|
|
redirector scripts can be a security risk and negatively affect the
|
|
reputation of your domain name.
|
|
</p>
|
|
<p>
|
|
Starting with HTML Purifier 3.1.1, there is also these substitutions:
|
|
</p>
|
|
<table>
|
|
<thead>
|
|
<tr>
|
|
<th>Key</th>
|
|
<th>Description</th>
|
|
<th>Example <code><a href=""></code></th>
|
|
</tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr>
|
|
<td>%r</td>
|
|
<td>1 - The URI embeds a resource<br />(blank) - The URI is merely a link</td>
|
|
<td></td>
|
|
</tr>
|
|
<tr>
|
|
<td>%n</td>
|
|
<td>The name of the tag this URI came from</td>
|
|
<td>a</td>
|
|
</tr>
|
|
<tr>
|
|
<td>%m</td>
|
|
<td>The name of the attribute this URI came from</td>
|
|
<td>href</td>
|
|
</tr>
|
|
<tr>
|
|
<td>%p</td>
|
|
<td>The name of the CSS property this URI came from, or blank if irrelevant</td>
|
|
<td></td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
<p>
|
|
Admittedly, these letters are somewhat arbitrary; the only stipulation
|
|
was that they couldn't be a through f. r is for resource (I would have preferred
|
|
e, but you take what you can get), n is for name, m
|
|
was picked because it came after n (and I couldn't use a), p is for
|
|
property.
