asp.net - How to deny users and redirect to login page when they type the same url in web page -

-

after login enter librarianform. when copy url , paste in new tab it's showing page without login. want redirect users login page when copy , paste url. how that.can please explain it. thank you.

asp.net has login mechanism can use. enable it, add below in web.config file. change loginurl attribute path of own login page. 

<configuration>     <system.web>         <authentication mode="forms">             <forms loginurl="~/login.aspx" timeout="28800" name="webappname" />         </authentication>     </system.web> </configuration>

to create asp.net authentication cookie need call formsauthentication.redirectfromloginpage can see below 

string username = ""; bool rememberme = true;  // implement own login mechanism , if user authenticated // set username variable , make call below formsauthentication.redirectfromloginpage(username, rememberme);

finally, logout user can call

formsauthentication.signout();

you can see link, describes similar mechanism
