AGAIN with the (413) Request Entity Too Large! Any help welcome...

Okay, I thought I had this stupid problem fixed. I'm running WCF with a client/server setup. Windows 7, VS 2012, .NET 4.5.

I've got the app working mostly fine, but when I started expanded testing I ran into this error AGAIN. I query list of policies, which are returned fine, select one from the list, and query for the entire selected policy. This is retrieved fine and displayed in the client... the policy edit form. The problem comes when I try to save even a small change... the data is rejected with the 413 message. Keep in mind that it is rejecting the exact same policy data that it just sent to the client. Not sure what's up, because I've got maxReceivedMessageSize set to 2 billion on both the client and the server.

Here is the app.config for the client:

Code:

---

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <!--<binding name="basicHttpBinding_IPolicyMaintenanceService" maxReceivedMessageSize="2147483647"/>-->
                <binding name="BasicHttpBinding_IPolicyMaintenanceService" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" receiveTimeout="00:30:00" sendTimeout="00:30:00" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:8080/UnicorMedServices/PolicyMaintenanceService"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IPolicyMaintenanceService"
                contract="PolicyServiceRef.IPolicyMaintenanceService" name="BasicHttpBinding_IPolicyMaintenanceService" />
        </client>
    </system.serviceModel>
</configuration>

And here is the web.config for the service:

Code:

So, the question becomes, since I've got the received message and buffer sizes set to 2 billion, and since the policy I'm testing this on is nowhere NEAR that large, what am I missing to get this to work? I thought I had this licked when it arose querying lists of policies, but I guess not.

ALL help is welcome...
