When jqgrid requests data, it always adds an nd= parameter to the query string.

Whats it there for?

I can see some point during development, to prevent caching – but I /want/ the data to be cached.

My server-side code sets an ETag header, and responds correctly to if-none-match headers. Everything works fine without the nd (ie, the request is made, and if there are no changes in the response, the server sends a “304 not modified”).

Am I missing something?
