Response.Filter属性:在数据发送出去前通过绑定的Filter来修改HTTP实体数据
应用场景(网站内容的GZIP压缩,多语言实现等等。。。)
定义:public Stream Filter{get;set;}
例如,实现网页压缩传输:
string str = Request.Headers.Get("Accept-Encoding");
if (str != null)
{
Stream filter = Response.Filter;
str = str.ToLower();
if (str.Contains("gzip"))
{
Response.Filter = new GZipStream(filter, CompressionMode.Compress);
Response.AppendHeader("Content-Encoding", "gzip");
}
else if (str.Contains("deflate"))
{
Response.Filter = new DeflateStream(filter, CompressionMode.Compress);
Response.AppendHeader("Content-Encoding", "deflate");
}
}
注意:该实例要在.net 2.0才能使用,可以在Page里面直接加入该功能.
