getClientType

public String getClientType(javax.servlet.http.HttpServletRequest request)
                     throws ClientDetectionException

This is the method used by the interface to set the client-type. ClientDetectionDefaultImpl currently uses the following algorithm.

     compare userAgent length and store the longest match
  if clientType not found 
     return the default clientType
 

Specified by:

getClientType in interface ClientDetectionInterface

Parameters:

request - The calling object passes in the HTTPServletRequest.

Returns:

The string corresponding to the client type.

Throws:

ClientDetectionException - if a default client type cannot be found

userAgentCheck

protected boolean userAgentCheck(String httpUA,
                                 String clientUA)

This method contains the algorithm used to compare the HTTPServletRequest user-agent versus the Client user-agent.

Parameters:

httpUA - The HTTPServletRequest user-agent

clientUA - The Client userAgent
