客户请求一张网页,如index.aspx,网页中含有缩略图控件,
2、 Index.aspx编译执行为HTML后被发送到客户端浏览器。这个控件生成了一个img标记,src属性指向一张该网页本身,但是后面附带的参数改变了。浏览器解析了,知道要向src属性获得一张图片。它开始向这个位置请求(也就是重新以新的附带参数请求这个网页)。
3、 ASP.Net获得了这个请求,index.aspx这个页面又开始执行,因为index.aspx中包含这个缩略图控件,控件就有机会识别这段特殊的参数,并且重新改写响应流,它会在文件系统中获得原始图像,然后根据你的要求,使用GDI.NET将原图重新按照新尺寸绘制,得到的新图是一个流对象,我们不存储它,而是将它直接附着在响应流中,发送给客户端。-Customer requests a page, such as the index.aspx, the page contains thumbnail control,
