1、可以对http最终输入、输出内容做任意的替换,代码如下:usingSystem;usingSystem.Collections;usingSystem.Configuration;usingSystem.Text.RegularExpressions;usingSystem.Web;usingSystem.Xml;usingSystem.Xml.Serialization;usingSystem.IO;usingSystem.Text;namespaceCnlamar.Web.HttpModule{  publicclassTextR

2、eplace:IHttpModule  {      publicvirtualvoidDispose()      {      }      publicvirtualvoidInit(HttpApplicationcontext)      {        context.ReleaseRequestState+=newEventHandler(this.context_ReleaseRequestState);      }      publicvoidcontext_ReleaseRequestState(objects

3、ender,EventArgse)      {        HttpApplicationhttpApplication=(HttpApplication)sender;        if(httpApplication.Response.ContentType.ToLower().IndexOf("image")<=-1)        {          TextReplaceFiltertextReplaceFilter=newTextReplaceFilter(httpApplication.Response.Filt

4、er);          textReplaceFilter.Encoding=System.Text.Encoding.GetEncoding(httpApplication.Response.ContentEncoding.BodyName);          textReplaceFilter.ReplaceRules=TextReplaceConfiguration.GetConfig().Rules;          httpApplication.Response.Filter=textReplaceFilter; 

5、       }      }  }  classTextReplaceFilter:Stream  {      publicboolIsRestore=false;      privateStreamm_stream;      privatelongm_position;      privateTextReplaceRulesCollection_ReplaceRules;            publicTextReplaceRulesCollectionReplaceRules      {        get   

6、     {          return_ReplaceRules;        }        set        {          _ReplaceRules=value;        }      }      publicEncodingEncoding      {        get        {          return_Encoding;        }        set        {          _Encoding=value;        }      }      p

7、rivateEncoding_Encoding=Encoding.UTF8;      publicoverrideboolCanRead      {        get        {          returntrue;        }      }      publicoverrideboolCanSeek      {        get        {          returnfalse;        }      }      publicoverrideboolCanWrite      {  

8、      get        {          returnfalse;        }      }      publicoverridelongLength      {        get
