<img src="<%=request.getContextPath()%>/maintenanceImage.imms?temp="+Math.random() name="image"/>
上面的 <img>标签如果去掉後面的temp参数不会出现以下问题，但是在有些浏览器就会有问题，认为那是同一个请求，直接在缓存里拿图片了。
我是用的jfreechart生成图片。
ServletUtilities.sendTempFile(filename, response);//可能就是这句的response有问题
就是这一句抛出异常。页面正常但是后台打出了错误信息，日志超多。
不知道为什么会抛出异常。
可能是我没有处理temp参数。
请问有什么办法可以解决此问题?
多谢各位。
