Hello, My issue is a little bit outside ISPConfig configuration. But it is linked with my server conf with ISP I am trying to set up a proxy: my backend : http://127.0.0.1:3000 extract of my vhost.conf : ProxyRequests Off ProxyPreserveHost On <Proxy *> AuthUserFile /etc/backend/back.htpswd AuthName "Service" AuthType Basic Require valid-user Options None </Proxy> ProxyPass "/" "http://localhost:3000/" connectiontimeout=10 timeout=300 keepalive=on ProxyPassReverse "/" "http://localhost:3000/" This works very well. I access it at : myvhost.tld But, I would like to acces it at : myvhost.tld/service So I edit my vhost.conf : ProxyRequests Off ProxyPreserveHost On <Proxy *> AuthUserFile /etc/backend/back.htpswd AuthName "Service" AuthType Basic Require valid-user Options None </Proxy> ProxyPass "/service" "http://localhost:3000/" connectiontimeout=10 timeout=300 keepalive=on ProxyPassReverse "/service" "http://localhost:3000/" It doesn't work ! curl http://localhost:3000/ answers "Found. Redirecting to /cluster/ns" In my browser, I see : myvhost.tld/cluster/ns instead of myvhost.tld/service/cluster/ns I try modify ProxyPassReverse, add Rewriterules, Redirect Permanent... without any success !
