How to use

getResponse

method

in

org.thymeleaf.context.IWebContext

/**
 * <p>
 *   Process an already-built URL just before returning it.
 * </p>
 * <p>
 *   By default, this method will apply the {@code HttpServletResponse.encodeURL(url)} mechanism, as standard
 *   when using the Java Servlet API. Note however that this will only be applied if {@code context} is
 *   an implementation of {@code IWebContext} (i.e. the Servlet API will only be applied in web environments).
 * </p>
 * <p>
 *   This method can be overridden by any subclasses that want to change this behaviour (e.g. in order to
 *   avoid using the Servlet API).
 * </p>
 *
 * @param context the execution context.
 * @param link the already-built URL.
 * @return the processed URL, ready to be used.
