Comment 11 for bug 1842701

hi all,

mybe i found a kind of same problem. in my configuration i used
the balancer manager behind a proxy

 -------------
|Bastian Host |
|Apache Proxy | -----------> LB Apache Balancer Manger
 -------------

and i struggle in the problem with an update from Ubuntu 18.04
which i described in the following bug report

https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1842701

on localhost with lynx i figure out error log entrys with every
submit and no update from the load data etc.

:~# tail -f /var/log/apache2/management_error.log
[Wed Sep 04 12:28:58.249737 2019] [proxy_balancer:error] [pid 14669:tid 140254497400576] [client 127.0.0.1:42844] AH10187: ignoring params in balancer-manager cross-site access
[Wed Sep 04 12:29:09.585221 2019] [proxy_balancer:error] [pid 14669:tid 140254623291136] [client 127.0.0.1:42848] AH10187: ignoring params in balancer-manager cross-site access

i can reproduce this within debian 10

:~# apt-get install apache2

:~# dpkg -l | grep apache2
ii apache2 2.4.38-3+deb10u1
ii apache2-bin 2.4.38-3+deb10u1
ii apache2-data 2.4.38-3+deb10u1
ii apache2-utils 2.4.38-3+deb10u1

i download the prior version from the module and compile that version

http://svn.apache.org/repos/asf/httpd/httpd/tags/2.4.40/modules/proxy/mod_proxy_balancer.c

:~# apxs2 -c -i mod_proxy_balancer.c

:~# systemctl restart apache2

:~# lynx 127.0.0.1:81/balancer-manager
:~# elinks 127.0.0.1:81/balancer-manager
Browser: http://192.168.56.211:81/balancer-manager

i can use the balancer manager as expected without any error log entry

i compiled also that version from https://svn.apache.org/viewvc?view=revision&revision=1865749
but with no luck.
