Your best bet here is to open the file into a textstream and read each 
line sequentially into a string variable, use the instring(InStr) function 
to return the position of the character you are looking for and Mid to 
retrieve it.
So....

Dim ts As TextStream
Dim str As String

Set fs=Server.CreateObject("Scripting.FileSystemObject")
Set ts=fs.OpenTextFile(Server.MapPath("/browseabit/new_sites/page.txt"), 1)
Do While Not ts.AtEndOfStream
str=ts.ReadLine
Response.Write(Mid(str,InStr(str,"u= "),InStr(str,"t= ")-InStr(str,"u= ")))
Loop
