The 
               Flags attribute is an integer value that specifies the tag information that is to be generated. The value is a bitmask of the following
               options:
               
            
 
            
            
               
               - 32 - HTTP header contains a unique user ID: 
                  (cross loadtest): VU=<Id>
                  
               
 
               
               - 128 - HTTP header contains information about the loaded document in the currently processed page. If it is a named frame then
                  the value starts with the frame name. Following a dot 
                  (.) the page-unique document number is appended. If embedded documents are cached, this number must be be progressional: 
                  PC=<FrameName>.<DocId>
                  
               
 
               
               - 256 - HTTP header contains a user-unique request Id: 
                  ID=<RequestId>
                  
               
 
               
               - 512 (default) - If the current request is issued in a page context, the HTTP header contains the specified timer name (if omitted,
                  the name is empty): 
                  NA=<TimerName>
                  
               
 
               
            
            
             For example, to enable all transaction information, specify 
               928 (32+128+256+512 = 928)
               
            
            
            Note: You must adopt 
               AppDynamics automatic transaction naming functionality to configure the additional parameters. 
               
            
            
             The 
               Probability attribute is a floating point value between 
               0 and 
               1, specifying the percentage of virtual users that should generate the HTTP tags.
