DO NOT REPLY [Bug 45434] New: ProxyPassReverse and balancer:// don'
t play nice
https://issues.apache.org/bugzilla/show_bug.cgi?id=45434
Summary: ProxyPassReverse and balancer:// don't play nice
Product: Apache httpd-2
Version: 2.2.9
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: All
AssignedTo: bugs@httpd.apache.org
ReportedBy: noah@hd.se
I believe there's an issue with how ProxyPassReverse handles redirects in
conjuction with mod_proxy_balancer.
See below for an example configuration which details the setup.
The browser requests /foo from the Apache HTTPd frontendserver. The frontend
server forwards the request to one of the balancer member servers (backend
servers).
The backend server decides /myservice/foo is a directory and redirects to
/myservice/foo/
The browsers get the following Location: header back:
Location: http://example.net/myservice/foo/
>From the below configuration you'd expect it to be just
"http://example.net/foo/", with "/myservice" zapped. That's at least how things
work when you're not using mod_proxy_balancer (see "Demo 3" below) at all.
An example configuration which details the issue in two ways with
mod_proxy_balancer (demo 1 and 2) and one example which doesn't use
mod_proxy_balancer and provides the expected result (demo 3)
<VirtualHost *>
ServerName example.net
# Demo 1: The following does not work:
ProxyPass /
balancer://mycluster/myservice/ stickysession=JSESSIONID|jsessionid
nofailover=On
ProxyPassReverse / balancer://mycluster/myservice/
<Proxy balancer://mycluster>
BalancerMember http://tomcat1.example.net:8180
BalancerMember http://tomcat2.example.net:8180
</Proxy>
# Demo 2: ..and neither does this
ProxyPass / balancer://mycluster/
stickysession=JSESSIONID|jsessionid nofailover=On
ProxyPassReverse / balancer://mycluster/
<Proxy balancer://mycluster>
BalancerMember
http://tomcat1.example.net:8180/myservice/
BalancerMember
http://tomcat2.example.net:8180/myservice/
</Proxy>
# Demo 3: This works though (but we can't do LB)
ProxyPass /
http://tomcat1.example.net:8180/myservice/
ProxyPassReverse / http://tomcat1.example.net:8180/myservice/
</VirtualHost>

Note,
ProxyPassReverse / balancer://mycluster/
was fixed by 2.2.9, and
ProxyPassReverse / balancer://mycluster/myservice/
is fixed for future 2.x releases, and proposed for backport to 2.2.12

For posterity, looks like this was fixed in r777191 for 2.2.x.

Your configuration is just wrong. In all three cases please add the following
*two* ProxyPassReverse directives:
ProxyPassReverse / http://tomcat1.example.net:8180/myservice/
ProxyPassReverse / http://tomcat2.example.net:8180/myservice/

I believe the bug for "Demo 1" is somewhere around this block at line 2502 in
modules/proxy/proxy_util.c.
l2 = strlen(u);
if (l1 >= l2 && strncasecmp(u, url, l2) == 0) {
u = apr_pstrcat(r->pool, ent[i].fake, &url[l2], NULL);
ap_log_error(APLOG_MARK, APLOG_DEBUG, 0, r->server,
"ppr: matched member (%s)", u);
return ap_construct_url(r->pool, u, r);
}
