[users@httpd] Possible bug in httpd-2.1.3-beta mod_proxy_balancer (URL arguments omitted)

["Dave O'Hair" <dohair@xxxxxxxxxxxxxxx>]

Hello Apache users,

 

I may have found a bug in httpd-2.1.3-beta mod_proxy_balancer.  Or more likely I just don’t have it configured properly.  Here’s the entries from httpd.conf:

 

    ProxyRequests on

    ProxyVia on

    <Proxy balancer://mycluster>

        Allow from all

        BalancerMember http://10.1.8.249:7002

        BalancerMember http://10.1.8.249:7003

    </Proxy>

    ProxyPass /SPECjAppServer balancer://mycluster/SPECjAppServer

    ProxyPass /Supplier balancer://mycluster/Supplier

 

The proxy/balance thing works great until I pass this URL to Apache:

 

    http://apachehost:80/Supplier/SupplierServlet?action="">

 

The URL that gets forwarded to the back-end server is missing the URL arguments (the “?action="" part).

 

The URL passed in to proxy_balancer_pre_request() already has the URL arguments stripped out.  I have put my own horrible hack of a solution into rewrite_url(), this does work but it is obviously not correct:

 

static int rewrite_url(request_rec *r, proxy_worker *worker,

                        char **url)

{

    <SNIP…>   

    *url = "" worker->name, path, NULL);

    /* new stuff */

    if (r->args) {

        *url = "" *url, "?", NULL);

        *url = "" *url, r->args, NULL);

    }

}
