非常新的问题 请原谅我
我创建了一个 asp.net 网站。 我假设当多人要求页面时, 每个人会得到网站的新实例。 但是, 如果网站在服务器上使用.jpg 图像并操纵图像, 那么每个人是否也会得到图像实例, 或者他们可以分享图像? 我认为我知道, 这也许是个愚蠢的问题, 但我想问一下 。
举例说: 用户登录到网站, 并给时间表增加时间。 根据时间表, 在显示每日时间的图像( grid.jpg) 上绘制一条蓝线。 然后将图像保存为 newgrid.jpg, 并显示给用户。 每个用户是否有办法获得一个他们只能看到的图像实例?
在 ASP.NET 中生成动态图像的一个很好的方法就是使用 < code> Handler 。 < a href=> 的答案是 < a href=> https://stackoverflow.com/ questions/21877/ consources/21877/ constitutionally- rendering-aspimage- from- blob- in- asp- net > > 。这里 < / a> 提供了一个很好、简单的例子。 在此情况下, 生成的图像从未触及本地文件系统, 只是在记忆中生成, 并返回客户 。
通常,网站对所有用户来说总是一样, 但每个用户都会为您设置特定设置的会话。 因此, 是的, 默认情况下, 所有人都会看到相同的变化( 和相同的内容 ) 。
