My servlet is deployed at http://vaninf.heliohost.org/2/url.jsp It returns 3 wrong parameters: request.getServerName() = 127.0.0.1 request.getServerPort() = 8080 request.getContextPath() = /vaninf_2 The expected correct data should be: request.getServerName() = vaninf.heliohost.org request.getServerPort() = 80 request.getContextPath() = /2 Can you support people tell me why, and how to fix it?
