Question

I’m currently working on a drilldown filter in MVC but I don’t really know how to make this the fastest and most flexible as possible.

Now my question is, how do you think they are doing this?
I’ve really no idea how to make this kind of drilldown but it seems they use some kind of hash they save for quick querying.

Maybe (pseudo)code anyone?

Answer 1

The answer after carefull looking at how they do it:

1. They send a normal http POST to the server with a querystring of all
   choices.
2. The server sends back a http GET which returns an URL with the
   hash.
3. The server caches the hash with the query so the next time the query is called it is faster.

Thanks everyone for your “usefull” responses.
