public static java.lang.String buildFullRequestUrl(javax.servlet.http.HttpServletRequest r)
public static java.lang.String buildFullRequestUrl(java.lang.String scheme, java.lang.String serverName, int serverPort, java.lang.String requestURI, java.lang.String queryString)
Note that the server port will not be shown if it is the default server port for HTTP or HTTPS (80 and 443 respectively).
public static java.lang.String buildRequestUrl(javax.servlet.http.HttpServletRequest r)
Under normal spec conditions,
requestURI = contextPath + servletPath + pathInfoBut the requestURI is not decoded, whereas the servletPath and pathInfo are (SEC-1255). This method is typically used to return a URL for matching against secured paths, hence the decoded form is used in preference to the requestURI for building the returned value. But this method may also be called using dummy request objects which just have the requestURI and contextPatth set, for example, so it will fall back to using those.
