The set of dispatchable processes is in a safe state if there exists at least one temporal order in which all processes can be run to completion without resulting in a deadlock.

urlencode() returns the URL encoded version of the given string. URL coding converts special characters into % signs followed by two hex digits. For example: urlencode("10.00%") will return "10%2E00%25?. URL encoded strings are safe to be used as part of URLs.
urldecode() returns the URL decoded version of the given string.

Microsoft introduced an alternative to CGI, the Internet Server Application Programming Interface (or ISAPI). ISAPI addresses one of the most limiting features of CGI applications. Each time a client requests the execution of a CGI application, the web server executes a separate instance of the application, sends in the user's requesting information, and serves the results of the CGI application's processing to the client. The problem with this approach is that a separate CGI application is loaded for each request. This can be quite a drain on the server's resources if there are many requests for the CGI application.ISAPI alleviates this problem by relying on dynamic link libraries (DLLs). Each ISAPI application is in the form of a single DLL that is loaded into the same memory space as the web server upon the first request for the application. Once in memory, the DLL stays in memory, answering user requests until it is explicitly released from memory. This increased efficiency in memory usage comes at a cost. All ISAPI DLLs must be thread-safe so that multiple threads can be instantiated into the DLL without causing problems with the application's function. ISAPI applications are normally faster than their equivalent CGI applications because the web server does not have to instantiate a new application every time a request is made. Once the ISAPI application DLL is loaded into memory, it stays in memory. The web server does not need to load it again

Standard Safe Mode can be accessed by pressing F5 when the "Starting Windows 9x" message is displayed on the screen.

The Startup Menu allows you to access all the standard Safe modes and others (including Normal, Logged, and standard Command Prompt Only modes), which can be accessed by pressing F8.

If the Normal option is selected, the system tries to restart as it would normally, loading all of its normal startup and Registry files. The Logged also attempts to start the system in normal mode, but keeps an error log file that contains the steps performed and outcome. This text file (BOOTLOG.TXT) can be read with any text editor or printed out on a working system.
