Hi,
This is exactly the problem.
When users connect to the application, they go through the squid, then
reach a login page where they enter login/passwd.
The application creates cookies including a PHPSESSION cookie.
Can squid use such cookie?

I am doing load balancing as sourcehash, so on IP source.
The problem is that about 80% of clients come from the same IP, so I
have a highly loaded backend, while other are sleeping.
So whatever you call it, on haproxy they call it session affinity LB,
my need is to use a round-robin load balancing, but, very important,
each user should always directed to the same backend.
So, the question remains "how do you identify a session?" (or maybe you could
rephrase it as "how do you identify a user?").
Can we do that with squid? avoiding user login on squid (userhash is not
convenient)?
You've already said that source IP is not a reliable indication of the user
(and this is very often true anyway), so what additional information exists in
the requests to identify a session / user?
Without knowing what application you're dealing with, we can't guess this for
ourselves.

Antony.

Hi,
I am using squid for years, maybe with basic features, and I have a
problem today with an app where I need to manage multiple backends, be
sure that a user is always sent to the same one because the app writes
on local disk, and I have 80% users coming from same IP.
Is this Squid operating in accelerator mode (in front of the server/s) or
in proxying mode (being used by the clients)?
So I need to load balance, not on the soucre IP, and I can't have a
login on squid to identify each user, because it will create a double
connexion procedure with the application login.
How does the app distinguish between different clients *without* Squid
being involved?
Is there a way that squid will recognize a new connexion, maybe same IP,
and load balnace it to any backend using round-robin? some affinity
session load balancing?
The first thing needed to answer that is a definition of "session".

Antony.
