Custom error pages
HTTP error responses (400, 403, 404, 405, 409 and 500) can be customized with custom error pages. To customize an error response, create file EVA_DIR/ui/errors/<code>.html, e.g. EVA_DIR/ui/errors/404.html for HTTP Error 404 (Not Found).
Custom error pages can have .j2 extensions as well. In this case, they are processed as SFA Templates.
If there is no way to define icon path with “link” HTML tag, put a file named “favicon.ico” in EVA_DIR/ui/ directory to override the default favicon.
