CanonicalizeUrl

See more Spider Examples

The CanonicalizeUrl method is a utility function that canonicalizes a URL into a standard form to avoid duplicates. For example, "http://www.chilkatsoft.com/" and "http://www.chilkatsoft.com/default.asp" are the same URL. AutoIt

$oSpider = ObjCreate("Chilkat.Spider")

;  Does a DNS lookup to find the default domain, which may or may not include the "www." depending on the DNS results.
;  Also domain names are converted to lowercase:
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.ChilkatSoft.com/") & @CRLF)

;  CanonicalizeUrl will drop the HTML fragment:
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com/purchase2.asp#buyZip") & @CRLF)

;  If a username/password is in the URL, it gets dropped:
ConsoleWrite($oSpider.CanonicalizeUrl("http://username:password@www.chilkatsoft.com/purchase2.asp#buyZip") & @CRLF)

;  Port 80 and 443 are dropped:
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com:80/purchase2.asp") & @CRLF)
ConsoleWrite($oSpider.CanonicalizeUrl("https://www.paypal.com:443/") & @CRLF)

;  Removes default pages:
;  default.asp, index.html, index.htm, default.html, index.htm, default.htm
;  index.php, index.asp, default.php, .cfm, .aspx, ,php3, .pl, .cgi, .txt, .shtml, .phtml
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com/index.asp") & @CRLF)
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com/index.asp") & @CRLF)
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com/index.php") & @CRLF)
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com/index.pl") & @CRLF)
ConsoleWrite($oSpider.CanonicalizeUrl("http://www.chilkatsoft.com/index.htm") & @CRLF)
