Final configuration which I have set in my apache : ...<snip> ProxyRequests Off ProxyPass /irj http://www.domain.com/irj ProxyPassReverse /irj http://www.domain.com/irj ProxyPass /logon http://www.domain.com/irj/logon ProxyPassReverse /logon http://www.domain.com/irj/logon ProxyPass /webdynpro http://www.domain.com/webdynpro ProxyPassReverse /irj http://www.domain.com/webdynpro ProxyPreserveHost On ProxyReceiveBufferSize 4096 ProxyBadHeader Ignore <snip>....
