Re: usage of querystring parameter instead of stickysession to route requests through proxy balancer (Apache Users)

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

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

Dear all

i know that is possible to use a "route" parameter into the proxy balancer definition and then set a stickysession cookie name into the ProxyPass setting.

Example:

ProxyPass / balancer://mycluster/ stickysession=MyCookie
ProxyPassReverse / balancer://mycluster/

<Proxy balancer://mycluster>

BalancerMember http://x.y.z.t:80 route=node01
BalancerMember http://x.y.z.u:80 route=node02

ProxySet lbmethod=byrequests

</Proxy>

If i set the cookie MyCookie=node01/02 i can route all requests to a specific node, and that's ok.

But....due to some architecture and application limitation i'm not able to operate with cookies, so i'm wondering if is possible to "detect" the route parameter directly from a query string parameter.

Example:

http://foo/test.php (dst is decided by proxy balancer rules)
http://foo/test.php?MyRoute=node01 (dst is node01)

http://foo/test.php?MyRoute=node01 (dst is node02)

Thanks to all in advance, bye!
