GWT Page Loading Issue.

Hi ,

I am facing following Issue.

I have devloped one GWT page .It takes long time to load and display the contents of page.
Sometime I need to refresh the page for proper loading of the page.

I Have also used the cache control filter as follows.

Note: Text content in the code blocks is automatically word-wrapped

1. public void doFilter (ServletRequest request, ServletResponse response, FilterChain filterChain)   
2.             throws IOException, ServletException   
3.     {   
4.         HttpServletRequest httpRequest = (HttpServletRequest) request;   
5.         String requestURI = httpRequest.getRequestURI ();   
6.   
7.         if (requestURI.contains (".nocache."))   
8.         {   
9.             Date now = new Date ();   
10.             HttpServletResponse httpResponse = (HttpServletResponse) response;   
11.             httpResponse.setDateHeader ("Date", now.getTime ());   
12.             // one day old   
13.             httpResponse.setDateHeader ("Expires", now.getTime () - 86400000L);   
14.             httpResponse.setHeader ("Pragma", "no-cache");   
15.             httpResponse.setHeader ("Cache-control", "no-cache, no-store, must-revalidate");   
16.         }   
17.   
18.         filterChain.doFilter (request, response);   
19.     }  

public void doFilter (ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException { HttpServletRequest httpRequest = (HttpServletRequest) request; String requestURI = httpRequest.getRequestURI (); if (requestURI.contains (".nocache.")) { Date now = new Date (); HttpServletResponse httpResponse = (HttpServletResponse) response; httpResponse.setDateHeader ("Date", now.getTime ()); // one day old httpResponse.setDateHeader ("Expires", now.getTime () - 86400000L); httpResponse.setHeader ("Pragma", "no-cache"); httpResponse.setHeader ("Cache-control", "no-cache, no-store, must-revalidate"); } filterChain.doFilter (request, response); }
