<H2><A NAME="_retrieving_browser_capabilities_from_a_cookie"></A><SUP></SUP>Retrieving Browser Capabilities from a Cookie</H2>
|
|
|
|
<P>A new way of determining client capabilities was added in IIS 5.0. If the client sends a cookie describing their capabilities as part of the request, your ASP page can create an instance of the Browser Capabilities component that adds the name value pairs specified by the cookie as properties.</P>
|
|
|
|
<P>For example, if the client sent a cookie that contained a name-value pair of userLanguage=Spanish, the Browser Capabilities component would add a userLanguage property and set the value for this property to Spanish. </P>
|
|
|
|
<P><span class=le><B>Important</B></span></P>
|
|
|
|
<P>If the METADATA#metatag exists in a file that is requested by the client as a result of a redirection using the <A HREF="/iishelp/iis/htm/asp/vbob9waa.htm">Server.Transfer</A> or <A HREF="/iishelp/iis/htm/asp/vbob9pid.htm">Server.Execute</A> methods, the metatag will be ignored by IIS. METADATA metatags in the file that actually contains the redirect, however, will be processed normally.</P>
|
|
|
|
<P>The following example demonstrates using a cookie to determine browser capabilities. Two files are required:
|
|
|
|
<UL type=disc>
|
|
<LI>Sendcook.htm runs on the client and uses DHTML to determine a list of properties that have been set on the client.</li>
|
|
|
|
<LI>Checkcap.asp creates an instance of the Browser Capabilities component and retrieves the properties from Sendcook.htm.</li>
|
|
</UL>
|
|
|
|
<P>--- SendCook.htm ---</P>
