open static fun fromServletMapping(request: HttpServletRequest): ServletUriComponentsBuilder
Prepare a builder from the host, port, scheme, context path, and servlet mapping of the given HttpServletRequest.
If the servlet is mapped by name, e.g. "/main/*", the path will end with "/main". If the servlet is mapped otherwise, e.g. "/" or "*.do", the result will be the same as if calling #fromContextPath(HttpServletRequest).
Note: This method extracts values from "Forwarded" and "X-Forwarded-*" headers if found. See class-level docs.
