Getting Started Spidering a Site

This is a very simple "getting started" example for spidering a web site. As you'll see in future examples, the Chilkat Spider library can be used to crawl the Web. For now, we'll concentrate on spidering a single site.

Download Chilkat Spider ActiveX

'  The Chilkat Spider component/library is free.
set spider = Server.CreateObject("Chilkat.Spider")

'  The spider object crawls a single web site at a time.  As you'll see
'  in later examples, you can collect outbound links and use them to
'  crawl the web.  For now, we'll simply spider 10 pages of chilkatsoft.com
spider.Initialize "www.chilkatsoft.com"

'  Add the 1st URL:
spider.AddUnspidered "http://www.chilkatsoft.com/"

'  Begin crawling the site by calling CrawlNext repeatedly.

For i = 0 To 10

    success = spider.CrawlNext()
    If (success = 1) Then
        '  Show the URL of the page just spidered.
        Response.Write spider.LastUrl & "<br>"
        '  The HTML is available in the LastHtml property
    Else
        '  Did we get an error or are there no more URLs to crawl?
        If (spider.NumUnspidered = 0) Then
            Response.Write "No more URLs to spider" & "<br>"
        Else
            Response.Write spider.LastErrorText & "<br>"
        End If

    End If

    '  Sleep 1 second before spidering the next URL.
    spider.SleepMs 1000
Next
