load balancing - Difference between session affinity and sticky session? -

What is the difference between session signage and sticky session in context Load Balancing Server?

I have seen those terms in a different word, but there are several ways to implement it: / P>

  1. Send a cookie on the first reaction and see this for the people who follow it, the cookie tells which real server sends.
    Bad If you have to support cookies-free browsers
  2. Participation based on the requester's IP address.
    Bad If it is not stable or many come through the same proxy.
  3. If you authenticate the user, then the partition based on the user name (this should be an HTTP supported authentication mode).
  4. The state is not needed.
    Let customers kill any server (send the state to the customer and send them back)
    This is not a sticky session, this is one way to avoid doing this.

I suspect that the sticky cookie can be done in a manner, and this relation can refer to # 2 and # 3 in some contexts, but it is not that I have noticed that Use it (or use it for yourself)

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created.
