[THIN] Re: WI and Netscaler's

Some interesting stuff from some design research we've been doing...

Why DNS Based Global Server Load Balancing (GSLB) Doesn't Work

http://www.tenereillo.com/GSLBPageOfShame.htm
http://www.tenereillo.com/GSLBPageOfShameII.htm
http://www.tenereillo.com/BrowserDNSCache.htm

This stuff is pretty full on, and very well written.

It would be interesting to get the view of a NetScaler Engineer on this.

Cheers.

Does this avoid the original issues? Nothing else should be required on the
WI. Where is your Netscaler placed on the network? (DMZ, LAN, same segment
as WI, etc.)

Hi Steve

We are doing what you suggest already.  Found the persistent session
timeout on Netscaler was ten minutes.  We have now set this to the same
length (720) of time as set in the web.config on the WI server.  I assume
no tweaks are needed on the WI servers?  PS this is WI3 with XPe FR3

      A persistent session with a cookie insert should do the trick, double
      check that the client is not blocking cookies!

      That would be great. I'm sure it's the netscaler piece that is not
      quite right....You didn't make any changes to WI to help?

            That should work right. I happen to be working with a Netscaler
            engineer today, I will see if I can learn more for you

            I believe so.  Think we are using a Cookie.

                  Are the sessions persistent? If so, what is the
                  persistence based on?

                  Hi All

                  Anyone have some pointers for getting WI to work well
                  with netscalers.  Essentially we have two WI 3 servers
                  and two Netscalers and load balance.  Having some issues
                  where WI seems to go into a loop and not display apps.
                  Also does not always display icons and sometimes straight
                  after logging in says the session has expired.  If you
                  close the IE session and go back in it works correctly.
                  Also if you go to both the WI server directly without
                  going via Netscalers it works correctly.

                  Tips and hints to look at ?
