Test if file exists before displaying with XMLHTTP

[Giles]

I have a left menu that is accessed and displayed via XMLHTTP (it resides on
the same server). Some sections of the web site don't have a "menu.asp", so
a "Page Not Found" page is returned, which doesn't look great in the menu
column.. Is there a way to know if a page exists before using
xml.responseText to pull it?
(apart from checking the actual text of the returned page to see if it
contains error-like words)
Thanks
Giles
(PS using xmlhttp instead of server.execute as the menu-page needs
processing before displaying)

 

[Slim]

Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FileExists(filespec)) Then
msg = filespec & " exists."
Else
msg = filespec & " doesn't exist."
End If


if you do not know the physical path you can try this

Set pc = Server.CreateObject("MSWC.PermissionChecker")

pc.HasAccess(url)


if you have permissions the file must exist

I have not checked this, but its worth a try

Just test the XMLHTTP.Status property after attempting to fetch it. If it's
404 the file didn't exist and the responseText will contain the sites 404
content.
