To set HTML and JSP pages without caching methods

HTTP header information expires tells the proxy server when its cached pages will expire.

The newly defined header information in the HTTP1.1 specification Cache-control can inform the browser not to cache any pages.

Basic methods for using Cache-control:

1) No-cache: Force cache to fetch new pages from the server
2) No-store: Cache does not save any pages in any environment

For HTML pages, join:

 <  meta  HTTP-EQUIV  = "Pragma"  " Span style= "color: #0000ff;" >= "No-cache"  >  <  meta  http-equiv  = "Cache-control"   CONTENT   >  meta  http-equiv  = "Expires"  Span style= "color: #ff0000;" > CONTENT  = "0"  >  

For JSP pages, join:

    <%          response.setheader ("Cache-control", "No-store");          Response.setheader ("Pragrma", "No-cache");          Response.setdateheader ("Expires", 0);       %>
