一般,response.expires写在页面的最上端,后面跟的是一个时间,就是过期的时间,0表示立即过期。 -1也是一样的道理,即是-9999也是一样的。 如:登陆验证码,使用Response.Expires = -1可以在登陆失败时点后退按钮后让验证码换一个,而不是原先的那一个。 Response.CacheControl = "no-cache" 设置不缓存在临时文件...
Cache-Control指定请求和响应遵循的缓存机制。在请求消息或响应消息中设置Cache-Control并不会修改另一个消息处理过程中的缓存处理过程。请求时的缓存指令包括no-cache、no-store、max-age、max-stale、min-fresh、only-if-cached,响应消息中的指令包括public、private、no-cache、no-store、no-transform、must-revalidate...
no-cahce并不是表示无缓存,而是指使用缓存一定要先经过验证 response header的no-cache和max-age=0和request header的max-age=0的作用是一样的:都要求在使用缓存之前进行验证 request header的no-cache,则表示要重新获取请求,其作用类似于no-store(可能你对这个结论很有怀疑,这不符合no-cache的设定。究其原因,在...
普通报头中的Cache-Control用于指定缓存指令，缓存指令是单向的（响应中出现的缓存指令在请求中未必会出现），且是独立的（一个消息的缓存指令不会影响另一个消息处理的缓存机制），HTTP1.0使用的类似的报头域为Pragma。 请求时的缓存指令包括：no-cache（用于指示请示或响应消息不能缓存）、no-store、max...
