ASP Browser Capabilities Component
ASP Browser Capabilities Component
The ASP Browser Capabilities component creates a BrowserType object that determines the type, capabilities and version number of a visitor's browser.When a browser connects to a server, a User Agent header is also sent to the server. This header contains information about the browser.
The BrowserType object compares the information in the header with information in a file on the server called "Browscap.ini".
Syntax
<%
Set MyBrow=Server.CreateObject("MSWC.BrowserType")
%>ASP Browser Capabilities Example
The example below creates a BrowserType object in an ASP file, and displays some of the capabilities of your browser:Example
<!DOCTYPE html>
<html>
<body>
<%
Set MyBrow=Server.CreateObject("MSWC.BrowserType")
%>
<table border="0" width="100%">
<tr>
<th>Client OS</th><th><%=MyBrow.platform%></th>

The Browscap.ini File
The "Browscap.ini" file is used to declare properties and to set default values for browsers.This section is not a tutorial on how to maintain "Browscap.ini" files, it only shows you the basics; so you get an idea what the file is all about.
The "Browscap.ini" file can contain the following:
[;comments]
[HTTPUserAgentHeader]
[parent=browserDefinition]
[property1=value1]
[propertyN=valueN]
[Default Browser Capability Settings]
[defaultProperty1=defaultValue1]
[defaultPropertyN=defaultValueN]| Parameter | Description |
|---|---|
| comments | Optional. Any line that starts with a semicolon are ignored by the BrowserType object |
| HTTPUserAgentHeader | Optional. Specifies the HTTP User Agent header to associate with the browser-property value statements specified in propertyN. Wildcard characters are allowed |
| browserDefinition | 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 |
| propertyN | Optional. Specifies the browser properties. The following table lists some possible properties:
|
| valueN | Optional. Specifies the value of propertyN. Can be a string, an integer (prefix with #), or a Boolean value |
