Figure 12-18. NTFS permissions in the Security tab of the file/folder properties dialog box On the Security tab, you ll see two distinct areas. The top area displays a list of users and groups for which permissions are defined. You can select an individual user or group by clicking on the name of the item. When an item is selected, the security permissions for that user or group appear below the user and group listing, showing whether the particular permissions is allowed or denied. Permissions explicitly defined for the file/folder are shown as normal check boxes, whereas any inherited permissions are shown as checked but grayed out check boxes. You can use the permission check boxes to either allow or deny a user or group the ability to perform certain actions, but you can t change the inherited permissions. Table 12-2 lists the various permissions and what it allows the user or group to do in regards to the file or folder.

SQL Server and Oracle connection pooling use a full-text match algorithm. That means any minor change in the connection string will thwart connection pooling, even if the change is simply to reverse the order of parameters or add an extra blank space at the end. For this reason, it s imperative that you don t hard-code the connection string in different web pages. Instead, you should store the connection string in one place preferably the <connectionStrings> section of the web.config file.

With both the SQL Server and Oracle providers, connection pooling is enabled and used automatically. However, you can also use connection string parameters to configure pool size settings. Table 7-2 describes these parameters. Table 7-2. Connection Pooling Settings

Click the Submit Page button to submit the web form back to the server one more time. There is no button-handling routine for this button on the server, so the only logic that executes is the Page_Load event handler. All this simple routine does is call GetClientState(). The GetClientState() routine pulls back values for all systems except the URL-encoding scheme, as shown in Figure 3-6.

Allows user or group to read the file, file attributes, extended attributes, and NTFS permissions. Allows the user or group all privileges associated with the Read permissions and the ability to execute the file if it is an executable (WinWord.exe, Notepad.exe, CMD.exe, and so on). Write permission on a folder allows the user to create files and subfolders in the folder and write attributes/extended attributes for folders. Write permission on a file allows the user to append or overwrite data in the file and write attributes/ extended attributes for the file.

The maximum number of connections allowed in the pool (defaults to 100). If the maximum pool size has been reached, any further attempts to open a connection are queued until a connection becomes available. (An error is raised if the Connection.Timeout value elapses before a connection becomes available.) The minimum number of connections always retained in the pool (defaults to 0). This number of connections will be created when the first connection is opened, leading to a minor delay for the first request. When true (the default), the connection is drawn from the appropriate pool or, if necessary, is created and added to the appropriate pool. Specifies a time interval in seconds. If a connection is returned to the pool and its creation time is older than the specified lifetime, it will be destroyed. The default is 0, which disables this behavior. This feature is useful when you want to recycle a large number of connections at once.

Here s an example connection string that sets a minimum pool size: string connectionString = "Data Source=localhost;Initial Catalog=Northwind;" + "Integrated Security=SSPI;Min Pool Size=10"; SqlConnection con = new SqlConnection(connectionString); // Get the connection from the pool (if it exists) // or create the pool with 10 connections (if it doesn't). con.Open(); // Return the connection to the pool. con.Close(); Some providers include methods for emptying out the connection pool. For example, with the SqlConnection you can call the static ClearPool() and ClearAllPools() methods. When calling

Figure 3-6. The ClientState.aspx web form after the Submit Page button postback GetClientState() is careful when accessing the state collections; it checks for null values and sets the name to a blank string where appropriate. This provides more reliable code that is capable of operating under failure conditions. The following excerpt of the code from Listing 3-2 reads values from ViewState. See Listing 3-2 for the details on the code for the other state mechanisms. // check the Viewstate for the viewstatename variable ViewStateLabel.Text = ""; if (ViewState["viewstatename"] != null) ViewStateLabel.Text = ViewState["viewstatename"].ToString();
