Use this step-by-step guide to apply the <location> tag to the Web.config file to configure access to a specific file and folder.
When using forms-based authentication in ASP.NET applications, only authenticated users are granted access to pages in the application. Unauthenticated users are automatically redirected to the page specified by the loginUrl
attribute of the Web.config file where they can submit their credentials. In some cases, you may want to permit users to access certain pages in an application without requiring authentication.
Configure Access to a Specific File and Folder

- Request any page in your application to be redirected to Logon.aspx automatically.
- In the Web.config file, type or paste the following code.
This code grants all users access to the Default1.aspx page and the Subdir1 folder.
Users can open the Default1.aspx file or any other file saved in the Subdir1 folder in your application. They will not be redirected automatically to the Logon.aspx file for authentication.
<authentication mode="Forms" >
<forms loginUrl="login.aspx" name=".ASPNETAUTH" protection="None" path="/" timeout="20" >
<!-- This section denies access to all files in this application except for those that you have not explicitly specified by using another setting. -->
<deny users="?" />
<!-- This section gives the unauthenticated user access to the Default1.aspx page only. It is located in the same folder as this configuration file. -->
<allow users ="*" />
<!-- This section gives the unauthenticated user access to all of the files that are stored in the Subdir1 folder. -->
<allow users ="*" />
- Repeat Step 3 to identify any other pages or folders for which you want to permit access by unauthenticated users.
