webService request failed with HTTP status 404

Question

I have problem with sending a big file via webService (System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse).

Everything works fine when the file is smaller then 20 MB, if it's bigger i get a response with 404 code.

Sounds like your file upload is timing out:

You can trap this error in your global.asax to see if this is the case:

Protected Sub Application_EndRequest(ByVal sender As Object, ByVal e As System.EventArgs)

    Dim context As HttpContext = HttpContext.Current.ApplicationInstance.Context
    If Not IsNothing(context) Then

        If Not context.Response.StatusCode = HttpStatusCode.OK Then

            'Detect file upload exceeded max length:
            If context.Response.StatusCode = 404 And
                context.Response.SubStatusCode = 13 Then
                'clear the previous error page content:
                context.Response.Clear()
                'redirect to custom error page:
                context.Server.Transfer("~/error.aspx?code=404.13", False)
            End If

        End If

    End If
End Sub

You can also increase the request length in your web.config like so:

<system.web>
    <httpRuntime maxRequestLength="29296" />
</system.web>

If there is a webservice reference in web application just delete that then Rebuild,run the webservice and then again add that webservice reference to the web application.
