Script example 4 Exercising ASP features Here are examples of the use of ASP features that have not been demonstrated in the other examples. Request.ServerVariables This call returns a number of useful parameters, including : HTTP_REFERER is the URL that called this script HTTP_HOST is the name of the host SERVER_NAME is the name of the host URL is the URL of this script SCRIPT_NAME is the URL of this script QUERY_STRING is the query string attached to the the URL HTTP_USER_AGENT is information about the browser HTTP_ACCEPT_LANGUAGE is the browser's language setting ALL_RAW is the raw HTTP header data ROOT_DIR is the DOS path of the Dynamic-CD root directory WINDOWS_TEMP_DIR is the path of the current user's Windows temporary directory Use the ROOT_DIR to locate support files - such as a database - on the CD. Use the WINDOWS_TEMP_DIR to write "temporary" information to the user's hard disk. Customisation could be supported by writing user settings to the Windows temporary directory, and recovering it when starting a new session. Writing to the user's hard disk should be done with care, after warning the user. ASP CODE <% for each thing in Request.ServerVariables Response.Write "<LI>" + thing + " = " Response.Write Request.ServerVariables( thing) next %> Server.ScriptTimeout If a script takes too long to process, Dynamic-CD terminates the script after 30 seconds. You can change this default value as shown in the following example. ASP CODE <% Server.ScriptTimeout = 10 '------------------------- 'get into an infinite loop WHILE TRUE WEND %> © Copyright 2000-2007 PHD Computer Consultants Ltd
