[GSS](7.2.z) UNDERTOW-1637 - Http-404 is returned when accessing protected application context resource without a trailing slash

Possible workarounds: use JBoss CLI with Undertow rewrite filter or expression-filter, aka: /subsystem=undertow/configuration=filter/rewrite=test-rewrite-slash:add(redirect= " true " ,target= "%U/" ) /subsystem=undertow/server= default -server/host= default -host/filter-ref=test-rewrite-slash:add(predicate= "equals(%R,/context)" ) or /subsystem=undertow/configuration=filter/expression-filter=app-slash:add(expression= "redirect( '%U/' )" ) /subsystem=undertow/server= default -server/host= default -host/filter-ref=app-slash:add(predicate= "method(GET) and regex(pattern=/context, value=%U, full-match= true )" ) modify the login.jsp file to send the POST always inside the context path: <form method= "post" action= "/context/j_security_check" enctype= "application/x-www-form-urlencoded" > Username <input type= "text" name= "j_username" /><br /> Password <input type= "password" name= "j_password" /> <input type= "submit" name= "submit" value= "Login" /> </form>

Use EAP 7.2.5 or later (but issue should be also reproducible on 7.2.4) Have a simple servlet application secured with a "FORM" login auth-method Access the application root context path without a trailing slash (e.g. "https://localhost:8443/context" )
