<s1 title="Description">
<p>
The <code>BrowserSelector</code> tests the user agent header field against

The <code>BrowserSelector</code> allows to define brower specific sitemap
processing.

</map:selectors>

]]></source>
</s2>
<s2 title="Configuration">
<p>
<!-- Explain the sitemap selector configuration, options when declaring
browser selector -->
The configuration section of <code>BrowserSelector</code> specifies
a mapping from user-agent strings to symbolic browser names.
</p>
<p>
Each browser element specifies a name attribute holding the symbolic
browser name
used in the test attribute expression. The attribute useragent contains
a matchable substring of some real user-agent values.
</p>
<p>
It is allowed to specify for a browser name more than one entry. This way
a symbolic browser name is matched by different user-agent substrings.
The snippet belows will yield true for <code>test="wap-handset"</code> if
the user-agent header contains <code>Nokia</code>, <code>UP</code>, or
<code>Wapalizer</code>.
</p>
<source><![CDATA[
...
<browser name="wap-handset" useragent="Nokia"/>
<browser name="wap-handset" useragent="UP"/>
<browser name="wap-handset" useragent="Wapalizer"/>
...
]]></source>
</s2>
<s2 title="Setup">
<p>
<!-- Explain the sitemap selector setup, ie options when using browser
selector -->
Setting up a <code>BrowserSelector</code> includes choosing the
<code><map:when></code> test expressions, and a
optional <code><map:otherwise></code> clause.
</p>
<p>
The test attribute of the <code><map:when></code> clause must match
a browser attribute name value. The value of the test attribute in a
<code><map:when></code> clause must be declared in a
<code>browser</code> name attribute.
</p>
</s2>
<s2 title="Effect on Object Model and Sitemap Parameters">
<p>
The <code>BrowserSelector</code> has no side effects on the object model,
or
any sitemap parameters.
</p>
</s2>
</s1>
<s1 title="Bugs/Caveats">
<p>
The <code>BrowserSelector</code> adds the response header attribute
<code>Vary</code> having value <code>User-Agent</code> indicating
that the response differ for different user agents. This information
especially meaningfull for an http-proxy server.

<s1 title="Description">
<p>
The <code>HostSelector</code> tests the <code>Host</code> header field from
the
request against the test attribute of the selectors when clause.
</p>
</s1>
<s1 title="Usage">
<p>
The <code>HostSelector</code> allows to define host specific sitemap
processing. This way Cocoon can do multi-homed sitemap processing.
</p>
<s2 title="Sitemap pipeline examples">
<p>
The snippet below uses a <code>HostSelector</code> named <code>host</code>,
and testing against symbolic host-sites which are configured in the
<code>host</code>
selector section.

<source><![CDATA[
<map:select type="host">
<map:when test="uk-site">
....

<map:when test="de-site">

<s2 title="Sitemap component configuration example">

defining symbolic host-site names for some host domains.
