I am using the latest version of jqGrid: 3.6.4

This seems like a simple problem (or at least it did before I spent a few hours on it):

When the grid sends a request to the server (to a controller action), its content-type is always:

application/x-www-form-urlencoded; charset=UTF-8

and I would like it to be:

application/json; charset=utf-8

but I can find no way of setting the content-type (there is no contentType option as you would find on a $.ajax call for example).

So just to clarify, I am not asking how to set the content-type on a jQuery server request, but specifically using jqGrid, which does not provide an obvious option for doing this.

Thanks, Nigel.
