SERVER-SIDE DETECTION

This section contains server-side examples that detect the Pocket PC operating system. The code snippets check to see whether the request comes from a browser on the Pocket PC operating system. If so, the code snippet redirects to a success.html page; if the request does not come from a Pocket PC device, the code will display that the request does not come from a Pocket PC device.

The code detects the Pocket PC by searching for the string "PPC" in the HTTP_USER_AGENT field sent by the browser along with the request. This technique can be used to redirect the user to different versions of a Flash movie depending on what device or browser the request is made from.

Note that only the first code example is documented, but all the code examples follow the exact same steps.

Macromedia ColdFusion

This ColdFusion code detects whether a request came from Pocket Internet Explorer running on a Pocket PC device.

 <! -          Get the user agent from the request sent by the browser.   ->  <cfset userAgent="#CGI.HTTP_USER_AGENT#">  <cfset isPocketPc = false>  <! -          Check to see that the user agent is not blank, and if it contains the string  "PPC".  If it does, that means the request came from a Pocket PC, otherwise, the request did not  come from a Pocket PC.   ->  <cfif (userAgent IS NOT "") AND (find("PPC", #userAgent#) GT 0)>           <cfset isPocketPc = true>  </cfif>  <cfif isPocketPc>           <cflocation url="success.html">  <cfelse>           You are <b>not</b> connecting with a Pocket PC device. </cfif> 

PHP

JSP

This JSP code detects whether a request came from Pocket Internet Explorer running on a Pocket PC device.
