WCF Service 413 no matter which config item I change - json

Question

I have been trying to figure this out for days, to no avail. This happens both when I try to debug in Visual Studio using IIS Express and with my production web site deployed to a machine running IIS 7.5.
I have called the service from a Visual Studio Unit Test using HttpWebRequest and in Fiddler 4, same errors. So I don't think this is a WCF client configuration, as I am not using one.
No matter what I change in my configuration file, I am always getting this exception:
"Exception thrown: 'System.ServiceModel.ProtocolException' in
System.ServiceModel.dll
Additional information: The maximum message size quota for incoming messages
(65536) has been exceeded. To increase the quota, use the
MaxReceivedMessageSize property on the appropriate binding element."
The below Web.config that I am attaching is for an application that is not at the root of my server.
I am calling using the json endpoint using Ajax.
I cannot for the life of me figure out why I am getting the 64K limit, especially given that I have added all of the items to the webHttpBinding as below.
I have also changed the httpRuntime element by adding the maxRequestLength item, changed the request filtering, the security settings, and a whole slew of other things that didn't make a difference.
Notice also that I have turned on tracing. The .svclog file didn't tell me anything more.
Thanks in advance for any help.

Try changing your config to this:
<service name="TravelRequestWebService.TravelRequestService">
<endpoint
address="web"
binding="basicHttpBinding"
bindingConfiguration="basicHttpBinding"
contract="TravelRequestWebService.ITravelRequestService" />
<endpoint
address="json"
binding="webHttpBinding"
behaviorConfiguration="jsonBehavior"
bindingConfiguration="webHttpBinding"
contract="TravelRequestWebService.ITravelRequestService" />
<endpoint
address=""
binding="basicHttpBinding"
contract="TravelRequestWebService.ITravelRequestService" />
</service>
The clue was the 64K default limit for the message size in the error message. This implied your binding configuration was not being used by WCF. The fact the configurations are named the same as the endpoint bindings added confusion.
