Hello,
I'm trying to achieve the following scenario using Apache 2.2:
- http://localhost/aaa/bbb?a=b must be proxied to
http://<BalancerMember>:1234/aaa/bbb?a=b (where <BalanceMember> is
either jack or jill)
- http://localhost/aaa/bbb?b=c must be proxied to
http://<BalancerMember>:1234/aaa/bbb?b=c
- http://localhost/aaa must be proxied to
http://<BalancerMember>:8080/aaa
- http://localhost/aaa/ must be proxied to
http://<BalancerMember>:8080/aaa/
- http://localhost/aaa/ccc must be proxied to
http://<BalancerMember>:8080/aaa/ccc
Assume the following httpd.conf snippet on localhost:
<VirtualHost _default_>
DocumentRoot /usr/local/apache2/htdocs
ServerName jack
ErrorLog logs/error_log
TransferLog logs/access_log
<IfModule mod_proxy.c>
ProxyPass /aaa/bbb balancer://balancer1
ProxyPass /aaa balancer://balancer2
<Proxy balancer://balancer1>
BalancerMember http://jack:1234/aaa/bbb
BalancerMember http://jill:1234/aaa/bbb
</Proxy>
<Proxy balancer://balancer2>
BalancerMember http://jack:8080/aaa
BalancerMember http://jill:8080/aaa
</Proxy>
</IfModule>
</VirtualHost>
When I try this I end up with the following undesired result:
- http://localhost/aaa/bbb?a=b proxies to
http://<BalancerMember>:1234/aaa/bbb/?a=b
- http://localhost/aaa/bbb?b=c proxies to
http://<BalancerMember>:1234/aaa/bbb/?b=c
Please note the added / in front of the ?
How can I fix this?
I initially used Apache 2.0 but that version seems to lack good
load-balancing and failover features, if I'm not mistaken. There were a
few things mentioned in the Apache2 Bible regarding load-balancing, for
instance using a DNS server to load-balance. However, these options
didn't seem feasible. That's why we switched to Apacha 2.2.
Just as some additional information, this was how I configured Apache
2.0 when we didn't use load-balancing and failover:
<IfModule mod_proxy.c>
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /aaa/bbb http://localhost:1234/aaa/bbb
ProxyPassReverse /aaa/bbb http://localhost:1234/aaa/bbb
ProxyPass /aaa http://localhost:8080/aaa
ProxyPassReverse /aaa http://localhost:8080/aaa
</IfModule>
This seemed to have the desired result:
- http://localhost/aaa/bbb?a=b proxies to
http://localhost:1234/aaa/bbb/?a=b
- http://localhost/aaa/bbb?b=c proxies to
http://localhost:1234/aaa/bbb/?b=c
Regards,
Jack...
