call/execute aspx page from another aspx page on page load

Hello experts,

I have requirement that one program should call aspx page which is on server and I can access it as http://www.abcd.com/main/test1.aspx?ID=1&Date=2&No=3

That caller program should execute every 8 hr. I think I can use schedule task program for executing at every 8 hr interval.

My question is how to execute aspx page and what type of file will be for caller program, e.g. console application, or window application or web application.

My caller program reads txt file containg some lines, split that lines "|" and should pass three parameters which read from txt file to aspx page.  (line will be "1"|"5"|"7")
I have done some partial part as below:

Dim txtfile As String
Dim sfileReader As System.IO.StreamReader
Dim sInputLine As String
Dim Arr(3) As String
Dim ID As String
Dim No As String
Dim Date As String

txtfile = "c:\rawfile.txt"
sfileReader = System.IO.File.OpenText(txtfile)

Do Until sInputLine Is Nothing
sInputLine = sfileReader.ReadLine()
System.Console.WriteLine(sInputLine)
sInputLine = sfileReader.ReadLine()
sInputLine = sInputLine.Replace("""", "")
Arr = sInputLine.Split("|")
ID = Arr(0)
Date = Arr(1)
No = Arr(2)
Loop

till this point I have three parameters to pass

Thank you
