- Several web interfaces we can able to access.
- The secure way of accessing web services is SSH Tunnel and proxy.
- These are the two components which we need to setup to access web interfaces related to web services without exposing the ports.
- To configure a proxy, if you are using Google Chrome, go to Chrome Web store, select foxyproxy standard and add it to chrome.
- Click on Enable Web Connection, copy the xml content and save as foxyproxy-settings-emr.xml
