[users@httpd] Re: usage of querystring parameter instead of stickysession to route requests through proxy balancer

[nik600 <ni...@gmail.com>]

Actually i've resolved using an explicit condition with mod_rewrite:

        <Directory /usr/share/php/imsl/com.imsl.mind.httpcluster/1.0>
                RewriteEngine on

                RewriteCond %{QUERY_STRING} ^(MyRoute=node1.*)
                RewriteRule (.*)
http://127.0.0.1:18002/%{REQUEST_URI} [P,L]

                RewriteCond %{QUERY_STRING} ^(MyRoute=node2.*)
                RewriteRule (.*)
http://127.0.0.2:18002/%{REQUEST_URI} [P,L]

                RewriteRule (.*)           balancer://mycluster/$1 [P,L]

        </Directory>

This configuration is working but is the "correct" one from your point of
view?

Thanks
