1. Patch Release Information 
========================================================================
    
    1.1 Resolved Known Issues 
    ====================================================================
    This Hotfix resolves the following issue(s): 

    
    Issue 1:      There is a buffer overflow issue when Deep Discovery 
                  Web Inspector handles a URL which has a length longer 
                  than 16K.
                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Solution 1:   This hotfix enables Deep Discovery Web Inspector to
                  handle a very long URL properly.


    1.2 Enhancements 
    ====================================================================
    The following enhancements are included in this Hotfix: 

    
    Enhancement 1:  This patch enables Deep Discovery Web Inspector to
                    support 5G inline HTTP(s) Web Traffic.
 		   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    
    Enhancement 1.1:  Deep Discovery Web Inspector provides a new 
                      high-end hardware Deep Discovery Web Inspector 
                      4200 to support 5Gbps inline HTTP(s) Web Traffic.

    Enhancement 1.2:  Deep Discovery Web Inspector 4200 adds a 10Gbps 
                      Fiber Networking Bypass Card by default.

    Enhancement 1.3:  A new license is available to enable the 5Gbps 
                      HTTP(s) traffic scan.
		     

    Enhancement 1.4:  Deep Discovery Web Inspector 
                      4200 supports 5Gbps Web traffic for bridge mode 
		      and proxy mode. Bridge mode can be deployed
		      from the admin console. But for 5Gbps proxy
		      mode, after running the deployment wizard from 
                      admin console, you need to do configuration using 
                      CLI (Command Line Interface).		  
					  
					  
		      A new CLI(Command Line Interface) is provided to 
                      enable the 5Gbps HTTP(s) proxy mode: 
                      # configure proxy I
					  
		      A new CLI(Command Line Interface) is provided to 
		      restore 5Gbps proxy mode to 1Gbps:
		      # configure proxy M
					  
	
    Refer to Deep Discovery Web Inspector 4200 Quick Start Card and 
    Deep Discovery Installation and Deployment Guide for the DDWI 
    4200 hardware details.
 

    Enhancement 2:  Deep Discovery Web Inspector adds a new CLI 
                    (Command Line Interface) to support restarting 
                    all web console related services separately.
