How to know a site's default index page form?

Usually see people use URL http : // a domain name . com

Question is :

How to find out that site's default page form?
example :
http : // a domain name . com / index .php
or
http : // a domain name . com / default .asp
or
http : // a domain name . com / index .html
or
http : // a domain name . com / welcome .htm
or
other name


Thanks,

 

Unless they link to it directly (e.g the 'Home' link), just guess until you find it. Look at other pages on the site and see what format they are (e.g: .php, .asp, .html) For example if all the pages on the site are .php, try index.php and default.php .... You could write a script to do this if necessary, but I don't think there is any other way to do this directly.

 

Yes, I need the script.

Could some one show the script?
Is it by checking the site's headers?

Thanks,

 

keep in mind that the default files for a directory can be changed to anything... but generally it won't be.

 

Another way to ask the question.

How to know an URL's whole URL?

 

If you want to know the default url of a site which u dont own then u just have to try all the extensions manually i guess

 

Here is a simple script in .NET:

   Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim strFiles As String
        Dim files() As String
        Dim domain As String
        strFiles = "index.html,index.htm,default.htm,default.html,index.asp,default.asp,index.aspx,default.aspx,index.php,index.cgi,index.pl"
        domain = "http://www.google.com/"
        files = strFiles.Split(",")
        For Each i In files
            If CheckURL(domain & i) Then MsgBox(domain & i) : Exit Sub
        Next
        MsgBox("Not Found")
    End Sub
    Function CheckURL(ByVal strURI As String) As Boolean
        Dim res As WebResponse
        Try
            res = WebRequest.Create(New Uri(strURI)).GetResponse()
            res.Close()
            CheckURL = True
        Catch ex As Exception
            CheckURL = False
        End Try
    End Function

Code (markup):

Must Import System.Net

You can add more file names if necessary...

 

You could achieve the same result with Classic ASP but would have to use XMLHttp and different error trapping technique.

 

it's hard to know...
