1, 使用java提供的方法设置http头信息，在jsp或者servlet中都可以 <br>
&lt;% <br>
response.setHeader(&quot;Pragma&quot;,&quot;No-cache&quot;); <br>
response.setHeader(&quot;Cache-Control&quot;,&quot;no-cache&quot;); <br>
response.setDateHeader(&quot;Expires&quot;, 0); <br>
%&gt; <br>
2, 使用HTML标记，如下： <br>
&lt;HEAD&gt; <br>
&lt;META HTTP-EQUIV=&quot;Pragma&quot; CONTENT=&quot;no-cache&quot;&gt; <br>
&lt;META HTTP-EQUIV=&quot;Cache-Control&quot; CONTENT=&quot;no-cache&quot;&gt; <br>
&lt;META HTTP-EQUIV=&quot;Expires&quot; CONTENT=&quot;0&quot;&gt; <br>
&lt;/HEAD&gt;&nbsp;      <br>   
      <br>   
        </td>
      </tr>
    </td>
  </tr>
