Unable to read vbLf and vbTab in POST request

Hello All. I'm afraid I'm in desperate need of help. I'm trying to understand why tabs and line feeds aren't coming through a POST request. Here's the code to reproduce:

POST request:

Code:

---

str = "accountRequest=<NewUser>" & vbLf & _
"Hello" & vbTab & "World" & vbLf & _
"</NewUser>"


Set objHTTP = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0")
objHTTP.open "POST", "service.asp", False
objHTTP.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objHTTP.send str

response.Write(objHTTP.responseText)

Set objHTTP = Nothing

---

service.asp

Code:

---

function w (str)
response.Write(str & "<br>")
end function

str = request.Form("accountRequest")

w(str)
w("Tabs: "& InStr(str,vbTab))
w("Lines: "& InStr(str,vbLf))

---

output:

Code:

---

HelloWorld
Tabs: 0
Lines: 0

---

Because they are written (and processed) in the code on the sending page. You would need to include them inside your quotations to POST them.

I used wireshark and it seems shows the "\t" representing the tab in the POST.

Finally figured out that ASP Request method doesn't preserve tabs if they're in the "\t" format (as opposed to URL encoded). However, PHP's $_POST does.
