ActiveX Upload fails on larger files

Oct 16 '12 at 04:07

I can upload very small files (e.g. 500 bytes), but anything larger I get the error shown below. This is IIS 7 on the server, and something is timing out after about 4 seconds. This happens in Firefox 15.01, IE8 and Chrome.

Output: bSuccess= 1 receiver.NumFilesReceived= 0

receiver.LastErrorHtml= ChilkatLog:


    DllDate: Aug 5 2012
    UnlockPrefix: NONE
    Username: BUZZARD:IUSR
    Architecture: Little Endian; 32-bit
    Language: ActiveX
    VerboseLogging: 0

    Assuming this is a POST...
    ContentLength: (NULL)
    numParts: 0


<form method="POST" enctype="multipart/form-data" action = "upload_test2.asp" >

Add a file attachment to the email:<br>
<input name=attach1 type=file size=20><br><br>
<input type=submit value="Upload and Email">

const constFolder = "c:\resp-tech\website\live\attachments"
set receiver = Server.CreateObject("Chilkat.UploadRcv")

'  Set a timeout just in case something hangs
'  This is a 20-second timeout:
receiver.IdleTimeoutMs = 20000
receiver.UploadDir = constFolder
receiver.SaveToUploadDir = 1

' Consume the upload.  Files are streamed to the UploadDir
bSuccess = receiver.Consume()

response.write "<p>bSuccess= " & bSuccess
response.write "<p>receiver.NumFilesReceived= " & receiver.NumFilesReceived
response.write "<p>receiver.LastErrorHtml= " & receiver.LastErrorHTML


To answer my own post, the problem was with the IIS: Behavior -> Limits Properties -> Maximum Requesting Entity Body Limit This was set to 200000 (20k) which explains the size problem Now set to 2000000 (2Mb) and all works fine
