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); }
and
Note: Text content in the code blocks is automatically word-wrapped
1. <filter>
2. <filter-name>gwtCacheControlFilter</filter-name>
3. <filter-class>com.test.GwtCacheControlFilter</filter-class>
4. </filter>
5.
6. <filter-mapping>
7. <filter-name>gwtCacheControlFilter</filter-name>
8. <url-pattern>/*</url-pattern>
9. </filter-mapping>
<filter> <filter-name>gwtCacheControlFilter</filter-name>
<filter-class>com.test.GwtCacheControlFilter</filter-class> </filter>
<filter-mapping> <filter-name>gwtCacheControlFilter</filter-name>
<url-pattern>/*</url-pattern> </filter-mapping>
Please let me know If something is missing.
