Hi All,
I have a basic question about mod_backhand and load balancing.
First take the simple situation. There is only one web server A and the
application root URL is
http://A.ffci.com/logon.jsp . The web application is a series of HTTP
request and response between the browser and
the webserver. We simulate the concept of state[ HTTP is inherently
stateless] using HTTPsession in the webserver.
Every thing is working fine.
Now we decide to create a server farm or web cluster by adding webservers B,
C . Here load balancing comes into
play. The user should type in the browser the same
http://A.ffci.com/logon.jsp but depending on the load it
should get translated to one of [ http://A.ffci.com/logon.jsp or
http://B.ffci.com/logon.jsp or
http://C.ffci.com/logon.jsp ].
The problem [ which I am not clear] is here. After first time the user gets
connected to a server all further requests should go to same server till he
closes the browser. How can I achieve this ?
To summarize we want load balancing [ automatic re-routing] to work only for
the URL http://A.ffci.com/logon.jsp
[ the application root].
Can we do this ?
Also if the server A has shutdown/crashed how can we transparently route
requests to B or C ?
Thanks in advance.
