<h2>ASP Browser Capabilities Component</h2>
<p>The ASP Browser Capabilities component creates a BrowserType object that determines the type, capabilities and version
number of each browser
that visits your site.</p>
<p>When a browser connects to a server, an HTTP User Agent Header is also sent
to the server. This header contains information about the browser (like browser
type and version number). The BrowserType object then compares the information
in the header with information in a file on the server called "Browscap.ini".</p>
<p>If there is a match between the browser type and version number sent in the
header and the information in the "Browsercap.ini" file, you can use the BrowserType object
to list the properties of the matching browser.
If there is no match for the browser type and version number in the Browscap.ini file, it
will set every property to
"UNKNOWN".</p>
<h3>Syntax</h3>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td><%<br />
Set MyBrow=Server.CreateObject("MSWC.BrowserType") <br />
%></td>
</tr>
</table>
<p>The example below creates a BrowserType object in an ASP file, and displays a table showing
some of the capabilities of the current browser:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td>
<pre><html>
<body></pre>
<pre><%
Set MyBrow=Server.CreateObject("MSWC.BrowserType")
%></pre>
<pre><table border="1" width="100%">
<tr>
<th>Client OS</th>
<th><%=MyBrow.platform%></th>
</tr><tr>
<td >Web Browser</td>
<td ><%=MyBrow.browser%></td>
</tr><tr>
<td>Browser version</td>
<td><%=MyBrow.version%></td>
</tr><tr>

<h2>The Browscap.ini File</h2>
<p>The "Browsercap.ini" file is used to declare properties
and to set default values for
browsers.</p>
<p>This section is not a tutorial on how to maintain "Browsercap.ini" files,
it only shows you the basics; so you get an idea what a "Browsercap.ini" file
is all about.</p>
<p>The "Browsercap.ini" file can contain the following:</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td>
<pre>[;comments]
[HTTPUserAgentHeader]
[parent=browserDefinition]
[property1=value1]
[propertyN=valueN]
[Default Browser Capability Settings]
[defaultProperty1=defaultValue1]
[defaultPropertyN=defaultValueN]</pre>
</td>
</tr>
</table>
<br />
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<th align="left">Parameter</th>
<th align="left">Description</th>
</tr>
<tr valign="top">
<td>comments</td>
<td>Optional. Any line that starts with a semicolon are ignored
by the BrowserType object</td>
</tr>
<tr valign="top">
<td>HTTPUserAgentHeader</td>
<td>Optional. Specifies the HTTP User Agent header to associate with the
browser-property value statements specified in propertyN. Wildcard
characters are allowed</td>
</tr>
<tr valign="top">
<td>browserDefinition</td>
<td>Optional. Specifies the HTTP User Agent header-string of a browser to
use as the parent browser. The current browser's definition will inherit all
of the property values declared in the parent browser's definition</td>
</tr>
<tr valign="top">
<td>propertyN</td>
<td>Optional. Specifies the browser properties. The following table lists some possible properties:<ul>
