What is the proper configuration for a WCF 4 REST service?

Sorry to post about this, but it's driving me nuts. I am using routes in the WCF4 REST template in VS2010. I set the maxreceivedmessagesize property to some gargantuan number, and it still gives me an HTTP status code 400 when I try to submit xml to the service. I turned on tracing, and the message tells me that it's still set to the default message size. This makes me think that the problem is some nuance in how I have my web.config set up. Could somebody take a quick peak at it and let me know what they think?

I've been around and around with this, and an extra set of eyes would be of great benefit to me. Thanks in advance!

OK, I figured it out; the problem was actually on the client. It wasn't serializing the object that I was trying to submit in the http post. When I checked it against a service on the test server, I corrected the xml for the post and now it's working properly. Thanks!
