Subject cookies,

All,

I am currently upgrading my web application from tomcat 3.x to tomcat 4.x.

To extract cookies I have a helper function,

    public static String getCookie( javax.servlet.http.HttpServletRequest
request,  String strName, String strDefault)
    {        
        javax.servlet.http.Cookie cookies[] = request.getCookies();
        
        for( int nCk=0; nCk < cookies.length; nCk++ )
        {
            if( cookies[nCk].getName().compareTo(strName) == 0 )
            {
                return unescape( cookies[nCk].getValue().toString() );
            }                
        }
        return strDefault;
    }

   public static String unescape(String strIn) 
   {
	/* you get the idea.... */
   }
	

however, on tomcat 4.0 the unescape is already being performed, so the
string returned is decoded twice (and therefore corrupted).

what is the best way to get the decoded cookie value that will work on both
version of tomcat ?

Thanks in advance,
Stuart James.
