  # server <- function(input, output, session) {
  #   # Get all URL parameters
  #   all_params <- sd_get_url_pars()
  #
  #   # Get specific parameters
  #   user_id <- sd_get_url_pars("user_id")
  #
  #   # Use in reactive expressions
  #   url_redirect <- reactive({
  #     params <- sd_get_url_pars()
  #     paste0("https://example.com?id=", params["id"])
  #   })
  #   sd_server()
