Path=Server.MapPath

[c676228]

Hi all,

I have one line code in my program, occasionaly I will receive the following
error:
"The Path parameter for the MapPath method did not correspond to a known path"

Path=Server.MapPath(sCertPath & "\" & order_id & ".pdf")


I am wondering what is happening since every time I check my error log, the
order_id value is not empty and sCertPath is a system variable.

Why does Server.Mappath fail?

can you share a hint?

Hi Betty,

From your descrpition, you ocassionally get some error at the
"Server.MapPath" call in your ASP application ,correct?

According to the codesnippet you provided, the Server.MapPath parameter is
concatenated via several string. As you said "sCerPath" is always
fixed(from environment variable), then the only part may vary is the
"order_id" variable, correct?

I've performed some research, it seems some possible causes is the path
contains some illegal characters, you can check the following thread:

m

Also, a kb article mentioned the ".." parent path code is not allowed in
Server.MapPath.

Path=Server.MapPath(sCertPath & "\" & order_id & ".pdf")

Instead of *guessing* as our Microsoft friend would have you do, why not
find out, for real?

<%
virtualPath = sCertPath & "/" & order_id & ".pdf" ' should always use /
in virtual!
path = "*BAD*"
On Error Resume Next
path = Server.MapPath(virtualPath)
oops = Err.Description
On Error GoTo 0
If path = "*BAD*" Then ' means that the MapPath got the error!
Response.Write "Server.MapPath reported error: " & oops _
& "<p>The virtual path given was: " & virtualPath & "<HR>" &
vbNewLine
Response.End ' or you can try some recovery code...up to you
End If
%>

Let the program find and diagnose the problem--WHEN it occurs--for you.
