Reviewing the code :

      ' URL
      If Trim(Request.QueryString("base_url")) <> "" And _
                  Request.QueryString("look_for") <> "" Then

Checks to see if the base URL and absolute path entered are empty or not. Note the base URL which you enter into 'base URL' field of Form 2 of 'addtodb.htm' page should be the base URL of your site you want to index e.g. http://www.yoursite.com or http://www.othersite.com/yoursitefolder etc.

And the absolute path should be the absolute path to the page on your site e.g. /default.asp or /folder/anotherpage.asp etc. So in FileSystemObject method of indexing site pages you have to enter two fields to make it work. Although only absolute path would have been enough to index a page but when we will be displaying the results to the user, there we will need complete path to the page so adding base URL is very important here.

      strURL = Request.QueryString("base_url") & Request.QueryString("look_for")

We concatenate the given base URL and absolute path to the page to get strURL. It is this variable which will be inserted into the database later.

      path = Server.MapPath(Request.QueryString("look_for"))

path contains the mapped physical location of the given page. Note Server.MapPath method translates the relative or absolute path of a file to a complete physical path to that file on that computer e.g. http://127.0.0.1/folder/file.asp will be translated to c:/inetpub/wwwroot/folder/file.asp.

      ' FileSystemObject
      Set fso = CreateObject("Scripting.FileSystemObject")

Creates FileSystemObject.

      ' File Object
      Set file = fso.OpenTextFile(path, 1, False)

Using FileSystemObject's OpenTextFile method we open the given page and create that page's file object.

      ' Reading the contents of the File into strFileContents
      strFileContents = file.ReadAll

We then use File object's ReadAll method to read all the content of that page into the variable strFileContents variable. Rest of the code is the same as 'addtodb.asp' page.

On the next page we create 'delfromdb.asp' to delete specific URLs from the Search Engine database if you would later want to remove some pages from the database.
