Apache mod_proxy url encoding

I have a REST service that accepts parameters in a form /{parameter} Also there is Apache2 that forwards requests to the websevice ``` <VirtualHost *:9091> AllowEncodedSlashes NoDecode LogLevel debug ProxyPass /webservice balancer://api/webservice <Proxy balancer://api> BalancerMember http://localhost:8030 </Proxy> </VirtualHost> ``` Parameters may contain encoded characters, like %2f (/) The problem is that Apache encodes these characters again, and Webservice receives %252F instead of %2F ``` [Mon Oct 15 13:59:24 2012] [debug] mod_proxy_balancer.c(46): proxy: BALANCER: canonicalising URL //api/webservice/Interface GigabitEthernet1%2F0%2F2 [Mon Oct 15 13:59:24 2012] [debug] mod_proxy_balancer.c(581): proxy: BALANCER (balancer://api) worker (http://localhost:8030) rewritten to http://localhost:8030/Interface%20GigabitEthernet1%252F0%252F2%20Utilization ``` If I request the webservice directtly, Tomcat/Jetty handles it find and service receives correct parameter.
