java - How to configure Tomcat for request.getHeader("remote_user")? -


i information on request.getheader("remote_user") within code. i'm entry level java/jsp developer , when program calls value of request, returns null. should capture user's credentials. haven't found definitive information on web or in textbooks regarding request. configure in tomcat, in browser or in code? unfortunately, can't post code when i'm finish code, send sa post on tomcat , request.getheader("remote_user") return proper value. when run in test configuration, on tomcat, request.getheader("remote_user") returns null. leads me believe tomcat. information or education can provide appreciated, thank you. sorry being able post code.

you should using httpservletrequest.getremoteuser().

the remote_user header mechanism between e.g. apache httpd , tomcat, , if don't have apache httpd in test setup, or isn't configured same production environment, won't it.
