9 - 9-18장상태관리 상태관리들어가기 클라이언트측상태관리옵션 ViewState ControlState HiddenField Cookie QueryString 서버측상태관리옵션 ApplicationState SessionState 데이터베이스

10 1. 상태관리 ( State Management) 들어가기 Without State Management With State Management Login.aspx Login.aspx Please enter your logon information: First Name John Last Name Chen Submit Greetings.aspx Web Server Please enter your logon information: First Name John Last Name Chen Submit Greetings.aspx Web Server Hello Hello John Chen I forget who you are!!

11 1>ASP.NET2.0 에서제공되는상태관리옵션 Server-Side Side State Management Application state Information is available to all users of a Web application Session state Information is available only to a user of a specific session Cookies Client-Side State Management Text file stores information to maintain state The ViewState property Retains values between multiple requests for the same page Profile Property Hidden Field Database In some cases, use database support to maintain state on your Web site Query strings Information appended to the end of a URL

12 2. 클라이언트측상태관리옵션 ViewState Hidden control retains values between multiple requests for the same page Control State Cookies Persistent cookies stored as a text file Query strings Information appended to the end of a URL Hidden fields Field retains values between multiple requests for the same page

13 1> 뷰상태 (ViewState) Server control state is stored in _VIEWSTATE, a hidden control on the.aspx page _VIEWSTATE stores state in a string value of name-value pairs <form name="form1" method="post" action="webform1.aspx" id="form1" runat="server"> <input type="hidden" name=" VIEWSTATE" value="ddw3nze0mtexodq7oz4=" /> 'HTML here </form> Maintain the state of select ASP.NET server controls vs. maintaining the state of all the ASP.NET server controls on a Web Form <%@ Page EnableViewState="False" %> <asp:listbox id="listname" EnableViewState="true" runat="server"></asp:listbox>

14 뷰상태 (ViewState) You can use the ViewState property to store your own state on the client-side. this.viewstate.add("name", txtname.text); // ViewState[ Name ] = txtnam.text; lblname.text = this.viewstate["name ].ToString();

15 2> 컨트롤상태 (Control State) ASP.NET 2.0 에서새로추가 ViewState는임의로해제될수있는반면, 컨트롤상태는임의로해제될수없다. Custom Control 구현시제대로동작하기위해필요 구현시프로그래밍이필요 컨트롤초기화도중에 RegisterRequiresControlState() 를호출 SaveControlState() 와 LoadControlState() 를재정의해야함

16 3> Hidden Field 동일한페이지및페이지간게시에도정보유지 HiddenField 및 HtmlInputHidden 컨트롤 보안에취약, 성능저하 <input type="hidden" / >

17 3> 쿠키 (Cookie) Used to maintain state Temporary/Non-persistent cookies Persistent cookies Less reliable than server-side state management options User can refuse or delete cookies Less secure than server-side state management options Limited amount of information Client-side restrictions on file sizes (4096 bytes) Client Computer Cookie Web Server

18 쿠키에정보저장 Creating a cookie using the Response and Request properties of the Page class HttpCookie objcookie = new HttpCookie("myCookie"); DateTime dt= DateTime.Now; objcookie.values.add("time", dt.tostring()); //objcookie[ Time ]=dt.tostring(); objcookie.values.add("forecolor", "White"); objcookie.values.add("backcolor", "Blue"); objcookie.expires = dt.addhours(1); Response.Cookies.Add(objCookie);

19 쿠키에서정보읽어오기 Read the cookie using Request.Cookies HttpCookie objcookie = Request.Cookies["myCookie ]; Retrieve values from the cookie lbltime.text = objcookie.values("time"); // lbltime.text = objcookie ["Time ]; lbltime.forecolor = System.Drawing.Color.FromName (objcookie.values("forecolor")); lbltime.backcolor = System.Drawing.Color.FromName (objcookie.values("backcolor ));

20 4> 쿼리문자열 (Query String) URL 에서? 이후에나오는문자열 페이지간의정보전달 보안에취약 URL에명시하므로길이제한 string s1 = Request.QueryString[ p1 ]; string s2 = Request.QueryString[ p2 ];

3. 서버측상태관리옵션 - 21 - Application state is a global storage mechanism accessible from all pages in the Web application Session state is limited to the current browser session Values are

21 3. 서버측상태관리옵션 Application state is a global storage mechanism accessible from all pages in the Web application Session state is limited to the current browser session Values are preserved through the use of application and session variables Scalability ASP.NET session is identified by the SessionID string Client Computer Web Server Application and Session variables SessionID

22 The Global.asax File Only one Global.asax file per Web application Stored in the virtual root of the Web application Used to handle application and session events The Global.asax file is optional

23 1> 응용프로그램상태 ( Application State) 웹응용프로그램모든모든사용자가접근할수있다. 모든세션이공유하는정보저장공간 웹서버메모리에저장 protected void Application_Start(Object sender,eventargs e) { Application["NumberofVisitors"] = 0; } Application.Lock(); Application["NumberOfVisitors"] = (int)application["numberofvisitors"] + 1; Application.UnLock(); lblnbvisitor.text = Application["NumberOfVisitors"].ToString();

24 2> 세션상태 ( Session Variables) Sessions are identified by 120-bit Session ID strings Setting session variables <= Session_Start event Session.Add("BackColor", "blue") ; Session["BackColor ] = "blue ; Reading session variables strbgcolor = Session["BackColor ]; Removing session variables Session.Remove["BackColor ] ;

25 Session Duration Sessions have a set duration time after last access Default is 20 minutes Session duration can be changed in Web.config <configuration> <system.web> <sessionstate timeout="10" /> </system.web> </configuration>

Scalable Storage of Application and Session Variables- 26 - By default, the session state is managed in process Disadvantage of in process storage: Not Scalable ASP.

26 Scalable Storage of Application and Session Variables By default, the session state is managed in process Disadvantage of in process storage: Not Scalable ASP.NET provides out of process storage of session state State can be stored in a SQL Server database or a state server Advantages of out of process storage: Scalable Web farm State server -Or- Session and Application variables Client SQL Session and Application variables

27 Saving Application and Session Variables in a Database Web.config에세션상태명시 1 Mode is set to SQLServer or StateServer <sessionstate mode="sqlserver" sqlconnectionstring= "data source=sqlservername; Integrated security=true"/> 2 SQL server 구성 c>aspnet_regsql.exe -S SampleSqlServer -E -ssadd 저장프로시저가포함된 ASPState 라는데이터베이스를만듭니다. 세션데이터자체는기본적으로 tempdb 데이터베이스에저장됩니다.

28 3> 프로필속성 (Profile Property) 사용자설정정보를저장하고참조하는데사용 세션상태와비슷하지만세션이종료되어도남아있다.

29 장웹응용프로그램관리 구성파일 (Configuration File) 관리도구사용

30 1. 구성파일 (Configuration File) > 구성파일이란? 웹서버나웹응용프로그램에대한구성ㅂ정보가들어있는.config 확장자를가지는 XML 파일 Machine.config file - Machine-level settings - Only one Machine.config file per Web server Web.config files - Application and directory-level settings Both Machine.config and Web.config files are: Well-formed XML camelcase Extendable

31 Understanding Configuration Inheritance CONFIG Machine.config Application-level Web.config file inherits settings from Machine.config file VirtualDir SubDir Web.config Web.config Settings in Web.config file that conflict override inherited settings Individual directories may have Web.config files that inherit from and can override application-level settings

32 구성정보 <anonymousidentification> <appsettings> <configuration> <appsettings> <add key="pubs" value="server=localhost; integrated security=true; database=pubs"/> <add key= FilePath1 value= \Files\MyFile /> </appsettings> </configuration> string strpubs = ConfogurationManager.AppSettings["pubs ]; string strfilepath = ConfogurationManager.AppSettings[ FilePath1 ]; <authentication> <authorization> <caching> <compilation>

33 구성정보 <httpruntime> <memebrship> <pages> <profile> <rolemanager> <sessionstate> <sitemap> <webparts>

35 장웹응용프로그램모니터링 추적 (Trace) Tracing Page-level Tracing Application-level Tracing 오류처리 (Error Handling)

36 Trace Object Inserting trace messages Trace.Write ("category", "message"); Trace.Warn ("category", "message"); Conditional execution with Trace.IsEnabled If (Trace.IsEnabled) { strmsg = "Tracing is enabled! ; Trace.Write("myTrace", strmsg); } Dynamically change state of trace Trace.IsEnabled = False;

37 페이지추적 (Page-level Trace) Page-level tracing displays trace statements only on the configured page Enabling page-level tracing <%@ Page Language="c#" Trace="true" %>

38 Viewing Trace Results

39 응용프로그램추적 (Application-level Tracing) Application-level tracing displays trace information for all pages in a Web application Enabling application-level tracing in the Web.config file <trace enabled="true" pageoutput="true" localonly="true"/> Set pageoutput=false in the Web.config file and trace results are viewable by trace viewer

40 Application-Level Trace Page Trace=True Trace=False Application Trace=True or Trace=False Trace=True or Trace=False Result Trace results are displayed on page Trace results are not displayed Trace not set Trace=True Trace results are displayed on page Application-level trace statements are displayed on individual pages

41 Tracing into a Component Import the System.Web Library using System.Web; Enable Tracing HttpContext.Current.Trace.IsEnabled = true; Call Trace methods HttpContext.Current.Trace.Write ("component", "this is my trace statement");
