Problem transfering Large Files using Web Service

[GKG]

Hi,
I am building an application to tranfer large files (1000MB) to the server using web service.
The client is the windows application using VB.net.

I have used DIME in the web service to transfer files.

The problem I am facing is that if I try to transfer files above 100MB then I get the following exception...
"execution Timed - Out".

I have made the following settings -
1. In web.config of the web service :
<system.web>
<httpRuntimeexecutionTimeout="1800"maxRequestLength="1024000"/>
</system.web>

2. In machine.config :
<httpRuntime
executionTimeout="1800"
maxRequestLength="1024000"
/>

The "execution Timed - Out" exception occurs before the 1800 seconds.

Can anybody why this happens and how to solve it???

Expecting help soon

Cheers,
GKG

Did you try the search services? I found a lot of interesting info and suggested methods to conquer this problem while searching "Large Files WebService"

One of these is MTOM, which is implemented is WSE 3.0 (web service enhancements) for .Net 2.0

Carl Franklin (www.dotnetrocks.com) did this very thing in a sample app as I posed this problem to him in how to handle large data transfers via web services. He used to have sample code on his web site but I can't find where it is, and I'm not sure if he posted this latest sample. It involved chunking, hash checking, etc. Give him an e-mail and see if he's willing to post his sample app where use uses the web service to pass up arrays of bytes chunks at a time. It should do the trick for you.

He also has links to a similar approach for .NET 1.1
