NET Development Server. Because of these differences there are scenarios where code that runs flawlessly in the development environment throws an exception or behaves differently when executed in production. Whenever the web server software handles an incoming request it associates that request with a particular security context. This security context information is used by the operating system to determine what actions are permissible by the request.
For example, an ASP. NET page might include code that logs some message to a file on disk. In order for this ASP. NET page to execute without error, the security context must have the appropriate file system-level permissions, namely write permissions on that file. NET Development Server associates incoming requests with the security context of the currently logged on user.
If you are logged on to your desktop as an administrator, then the ASP. NET Development Server will have the same access rights as an administrator. However, ASP. By default, the Network Service machine account is used by IIS versions 6 and 7, although your web host provider may have configured a unique account for each customer. What's more, your web host provider has likely given limited permissions to this machine account.

Point your browser to this file; you should see a message similar to the one shown in Figure 1. At this point you should either see the book review page as normal or the error message shown in Figure 2. Some web host providers grant write permissions to the anonymous ASP.
NET machine account, in which case the page will work without error. If, however, your web host provider prohibits write access for the anonymous account then an UnauthorizedAccessException exception is raised when the TYASP The good news is that most web host providers have some sort of permissions tool that allows you to specify file system permissions in your website.
Grant the anonymous ASP. To create text buttons and image placements, HTML is used extensively. Further, the Secure Sockets Layer SSL Protocol, developed by Netscape in order to transfer documents through the internet, has a cryptographic system that puts to use a couple of keys to undertake data encryption.
