Hi - I create a input box as follows:
<INPUT id="inpJobDescE mpSpec" style="BORDER-RIGHT: gray thin solid;
BORDER-TOP: gray thin solid; Z-INDEX: 181; LEFT: 232px; BORDER-LEFT: gray
thin solid; WIDTH: 640px; BORDER-BOTTOM: gray thin solid; POSITION: absolute;
TOP: 400px; HEIGHT: 22px" tabIndex="27" type="file" maxLength="250" size="87"
name="inpJobDes cEmpSpec" RunAt="Server">
to allow the user to select a file which I want saved to a SQL Server
database.
On the save I then run this code to insert the document into the database:
'only try and attach file if there is one specified
Dim impersonationCo ntext As
System.Security .Principal.Wind owsImpersonatio nContext
Dim currentWindowsI dentity As
System.Security .Principal.Wind owsIdentity
currentWindowsI dentity = CType(User.Iden tity,
System.Security .Principal.Wind owsIdentity)
impersonationCo ntext = currentWindowsI dentity.Imperso nate()
'Insert your code that runs under the security context of
the authenticating user here.
If Len(Trim(inpJob DescEmpSpec.Val ue)) <> 0 Then
Dim fs As New System.IO.FileS tream _
(inpJobDescEmpS pec.Value,
System.IO.FileM ode.OpenOrCreat e, _
System.IO.FileA ccess.Read)
Dim MyData(fs.Lengt h) As Byte
fs.Read(MyData, 0, fs.Length)
fs.Close()
.JobDescEmpSpec Doc = MyData
.UpdateDocument = True
Else
Dim MyData(0) As Byte
.JobDescEmpSpec Doc = MyData
.UpdateDocument = False
End If
impersonationCo ntext.Undo()
(where I am setting MyData to a byte property of my data class)
This works perfectly fine in the development environment (my PC has Visual
Studio and is the web server connectin to a SQL server database on out
network.
I can browse for and attach files with or network paths (C:\Folder\File .doc
or \\Server\Share\ Folder\File.doc )
If I connect to the website on my PC from another PC the local drive upload
works fine (C:\Folder\File .doc) but the network upload fails because
somewhere along the way the backslashes are beibng removed so it is trying to
access file \ServerShareFol derFile.doc
Anyone any idea why this is?
Thanks in advance

The problem is that inside strings, the backslash is considered an escape
to allow special characters. So you may use double slashes.
the problem is credentials forwarding. by default (and with ntlm impossible)
its not allowed to forward user credentials from a second machine to a third
(1 hop rule).
when you are on your local box, iis and asp.net has a primatuy token and can
talk to network resouces on other machines. if you connect to your pc from
another, then iis and asp.net no longer have a primary token can can not use
the token to talk to another resource.
if you switch to kerberos and enable forwarding you will able to do what you
want. http://support.microsoft.com/default...b;en-us;810572

I work for an animal hospital trying to use PHP to store an animal's

I can browse for the xray on the local desktop computer then click

the image 'xray.tif' each time they click "Upload Image" instead of

I have an intranet LAMP server and I use PHP to upload files. It is of course faster to download the same file than to upload it.
I understand ISPs throttle their network for download speed, than upload since most people download from the internet vs upload.
My question is if it's a local intranet with a couple of users, why is it faster to download the same exact file vs when I uploaded it a minute ago.
Does it have to do with HTTP...
