To stop unnecessary memory usage, we are going to give // web crawler no session management. This way, they don't have to worry about cookie // acceptance and object persistence (except for APPLICATION scope). Here, we are // using short-circuit evaluation on the IF statement with the most popular search // engines at the top of the list. This will help us minimize the amount of time that // it takes to evaluate the list. // Create a lowercase version of the user agent so we can run without NoCase checks. strTempUserAgent = LCase( CGI.http_user_agent ); // Check user agent. if ( (NOT Len(strTempUserAgent)) OR // We are gonna try to optimize even a little bit more. A good number of the spider // names end in "bot". If we check for names that have BOT ending on a word boundary, // we can eliminate several of the other spider checks. The bot\b search here takes // care of the spiders that are now commented out below. As you can see, it takes // the place of 18 different spider Find()'s.
