    I have been working with the people of SurfControl for 
    a couple of weeks now and all they say is that they 
    will submit it as a bug in the software and try to get 
    a fix out in the next couple of months. So here goes….
    You can bypass the software by using a proxy sever 
    before your traffic is looked at by SurfControl Super 
    Scout. After talking with the people at SurfControl it 
    has become apparent that you may bypass all of their 
    software that is meant for Internet monitoring. I have 
    not been able to test it though. They only look at 
    packets that have the HTTP GET request and "Host:" 
    information in it. If you split up the request so that 
    HTTP GET request is not in the same packet as 
    the "Host:" information then you will bypass the 
    software. 
    You can easily do this by using a proxy server before 
    you get to the node that is doing the Internet 
    monitoring. If you have Compaq PC's or servers that 
    are not patched you can proxy off the Insite Manager 
    software
    (http://www.compaq.com/support/files/server/us/dow
    nload/9609.html). If you have PERL installed you can 
    use RFProxy, HTTPush or Pudding. These programs 
    were intended for the testing of IDS evasion 
    techniques but work wonders for Internet 
    monitoring/blocking evasion.
