本文實例講述了Asp.net程序優化js、css實現合并與壓縮的方法。。具體實現方法如下：

訪問時將js和css壓縮并且緩存在客戶端,
采用的是Yahoo.Yui.Compressor組件來完成的,用戶可以點擊此處本站下載。

創建一個IHttpHandler來處理文件

代碼如下:
public class CombineFiles : IHttpHandler
{
        private const string CacheKeyFormat = "_CacheKey_{0}_";

        private const bool IsCompress = true; //需要壓縮

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }

        public void ProcessRequest(HttpContext context)
        {
            HttpRequest request = context.Request;
            HttpResponse response = context.Response;

            string cachekey = string.Empty;

            string type = request.QueryString["type"];
            if (!string.IsNullOrEmpty(type) && (type == "css" || type == "js"))
            {
                if (type == "js")
                {
                    response.ContentType = "text/javascript";

                }
                else if (type == "css")
                {
                    response.ContentType = "text/css";
                }

                cachekey = string.Format(CacheKeyFormat, type);

                CompressCacheItem cacheItem = HttpRuntime.Cache[cachekey] as CompressCacheItem;
