数据缓存依赖、图片防盗链url重写

数据库缓存依赖1、数据库缓存依赖-S服务器名称  -E集成身份验证  -ed启动 -d数据库名称  -et指定缓冲依赖的表名 -t表名在vs2010的命令提示符中运行（切换到aspnet_regsql.exe所在的目录）aspnet_regsql.exe -S 127.0.0.1 -E -ed -d myphotos -et -t photos缓存依赖禁用该数据库aspnet_regsql -S . -E -dd -d myphotos2、依赖于数据库的web.config配置<system.web>    <caching>      <sqlCacheDependency enabled="true">        <databases>          <add name="myphotos" connectionStringName="connectionString" pollTime="500"/>        </databases>      </sqlCacheDependency>    </caching>3、 System.Web.Caching.SqlCacheDependency dep = new System.Web.Caching.SqlCacheDependency("myphotos", "photos");                Cache.Insert("list", list, dep);进程外session    StateServer  对象必须可序列化        1.开始 ASP.NET 状态服务  services.msc        2.配置webconfig            <sessionState mode="StateServer" stateConnectionString="tcpip=localhost:42424"></sessionState>        //        3.如果是远程的stateserver配置注册表  regedit            HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection            设置成1    图片防止盗链 void Application_BeginRequest(object sender, EventArgs e)    {        if (Request.RawUrl.Contains("images/"))        {            if (Request.UrlReferrer == null || !IsSameDomain(Request.UrlReferrer, Request.Url))            {                                Response.ContentType = "image/jpeg";                string path = Request.MapPath("~/daolian.jpg");                Response.WriteFile(path);                //结束请求                Response.End();            }        }    }    //判断两个域名是否相等    bool IsSameDomain(Uri u1,Uri u2)    {        return Uri.Compare(u1, u2, UriComponents.HostAndPort, UriFormat.SafeUnescaped, StringComparison.CurrentCultureIgnoreCase) == 0 ? true : false;    }url重写一、原理void Application_BeginRequest(object sender, EventArgs e)    {     //url重写        HttpApplication app = sender as HttpApplication;        string url = app.Request.RawUrl;        Regex r = new Regex("/(\\d+)/details\\.htm",RegexOptions.IgnoreCase);        Match m = r.Match(url);        if (m.Success)        {            string id = m.Groups[1].Value;            app.Context.RewritePath("~/PhotoDetails.aspx?id=" + id);        }    } 二、urlRewriter1、在<configSections>节点加入 <section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter" />2、在</configSections>之后加入      <RewriterConfig>    <Rules>      <RewriterRule>        <LookFor>~/(\d{4})/(\d{2})/Default\.aspx</LookFor>        <SendTo>~/Default.aspx?ID=$1</SendTo>      </RewriterRule>    </Rules>  </RewriterConfig>3、<httpHandlers>中加入<add verb="*" path="*.aspx" type="URLRewriter.RewriterFactoryHandler, URLRewriter" />或者 <httpModules>加入<add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter" />
