NLB and IIS
am 01.07.2007 05:17:26 von Damian Stalls
I would like to use NLB with a web farm I currently maintain. My
question is how does the NLB service decide which server to place
each
client or request. My understanding of IIS6 is that each request
made
by a client is treated a new request and not an extension of the
previous request.
Basically if i search through the browser everyone who lives in "Los
Angeles" and if i get 15 pages of content every time I click "Next"
to
see the next page a different server could be handeling the request.
Is this the case or can NLB tie a remote client session to a specific
server in the farm and all requests are only handeled by that server
(for a period of time)? Any feedback would be appreciated.
(I ask because my application currently does not remember the user
state... if a different server handles the request when I click
"Next" the entire search will be reset and I will be looking at
everyone as opposed to my search criteria).

Inside the NLB setting, ensure you set it to single affinty, meaning session
stickyness.
If a client established a connection with 1 specific node, with the
configuration - it will stick to that one host until that particular session
end.

When the request first came in to the node, IIS establishes a session with
the requestor.
it end when a) session timeout, b) iis service restart, c) manually ending
the sessions, e.g. logoff, etc
