Hello,

I'm receiving an HTTP 400 Bad request when invoking a .Net WSE2 Web Service
with a DIME attachment.

If I send a short file, say 500 KB, everything runs fine, but when I send a
bigger one (2 or 3MB), I receive a Bad Request.

After reading some posts about this issue, I created appropriate entries in
Web.config to allow large requests, but the problem persists.

I have the following values in Web.config, in their appropriate sections:

<!-- web settings -->
    <!-- Set the maximum http request length (in KB), so that large attachments
are supported -->
    <httpRuntime maxRequestLength="262144"/>

<!-- wse 2 settings -->
    <messaging>
        <!-- Set the maximum http request length (in KB), so that large
attachments are supported -->
        <maxRequestLength>262144</maxRequestLength>
    </messaging>

I notice the following event recorded in Application Event:

HTTP/ASMX Message Receive Failure:
Microsoft.Web.Services2.Dime.DimeFormatException: WSE309: The Type_T of the
middle record chunk must not be 0 (Type_T=Unchanged).

Any clue?

Thanks,
