Answer 1

There are a lot of places where you can try to implement the authentication of your odata service. Here is some examples:

You can try to solve your problem with QueryInterceptor (see http://msdn.microsoft.com/en-us/library/dd744842.aspx and http://msdn.microsoft.com/en-us/library/dd744837.aspx).

Another way is usage of ProcessingPipeline event handlers. It will be called not only for GET requests.

You can look at Authenticating WCF DataServices. It's depend on your implementation of authentication, but it can be this example is what you want. One use here headers for authentication information, you can use URL parameter only if it is required in your implementation.

To access URL parameters you can use Request.QueryString (see Application_BeginRequest from http://josheinstein.com/blog/index.php/2010/05/wcf-data-services-format-json/)
