*]QTL QV\MZIK\Q^M LQIOZIU[ MI[QMZ \PIV aW] M^MZ QUIOQVML supports both the native FTP implementation—which is not secure as it sends credentials over the network in plain text—as well as the two standardized secure implementations: FTP over SSL and SFTP. Once connected to an FTP site, the FileZilla user interface consists of four mands sent to the FTP server and the corresponding response. This low-level information is quite helpful for developers and other savvy users when troubleand folders on the local computer while the third pane lists those on the FTP one location to the other, simply select the items from one pane and drag them over to the other pane. The current activity and pending list of actions are listed in the transfer queue, which is displayed in the bottom pane. In addition to the client application, the FileZilla project includes a free, open-source FTP server implementation. Price: Free; source code available (Visual C++) sourceforge.net/projects/ﬁlezilla by copying frequently used data from a slow data source to a faster one. For data-driven applications, this usually entails caching data retrieved from databases or Web services into the local computer’s memory. Caching is easiest to implement when but becomes much more challenging if multiple applications need to work with a common cache. For example, large Web sites typically use a server farm that consists of several computers all serving the same content. As each request arrives, it is assigned to one of the computers in the farm. However, if information is cached in the memory of one computer in the farm, it is not accessible to the cache in another, thereby reducing the effectiveness of the cache. One solution to this problem is to move the cache to a centralized data store, such as a database, or to designate one of the servers in the farm as the cache server, which stores the only copy of the cache. The problem with centralized cache stores is that they introduce a single point of failure and can serve as a bottleneck. To overcome the limitations of a single, centralized cache store, consider using NCache 3.1 from Alachisoft.
