using System.Configuration;

using System.Web.Caching;
namespace Module.config
{
[Serializable()]
[XmlRoot("RewriterConfig")]
public class UrlConfiguration
{
public UrlConfiguration() { }
/// <summary>
/// 返回配置文件中的RewriterConfig配置節.提示信息.該數據緩存依賴於文件
/// </summary>
/// <returns></returns>
public static UrlConfigurationSection GetConfig()
{
if (HttpContext.Current.Cache["RewriterConfig"] == null)
{
HttpContext.Current.Cache.Insert("RewriterConfig", ConfigurationManager.GetSection("RewriterConfig"), new CacheDependency(HttpContext.Current.Server.MapPath("~/VirtualPath.xml")));
HttpContext.Current.Cache.Insert("IsSetSeoXmlByVirtualPath", "Yes");
}
else
{
if (HttpContext.Current.Cache["IsSetSeoXmlByVirtualPath"] != null)
{
HttpContext.Current.Cache["IsSetSeoXmlByVirtualPath"] = "No";
}
else
{
HttpContext.Current.Cache.Insert("IsSetSeoXmlByVirtualPath", "No");
}
}
return (UrlConfigurationSection)HttpContext.Current.Cache["RewriterConfig"];
}
}
}
至此。已經寫完了。其實這個東西很早了，已經很多站在使用。最後你還可以開發一個管理的一個頁面對xml進行管理。很方面。呵呵呵。很多還不完善，需要大家一起來完善。
