Add header with total number of matched items

Hi,

I’m writing a small app retrieving data from your API, using skip & limit, and displaying data in a paginated table.

Suppose that I want only the flight_id field for the launches endpoint, with 10 items per page. To know how many pages are available, I must do one of the following:

• Either fetch the whole set with filter=flight_id & limit=999, but it is heavy and I prefer load data lazilly
• Or do 2 requests:
  • one to fetch my data, with skip=0, limit=10 & filter=flight_id
  • and the other with limit=999 & filter=a_non_existent_field, to get only empty objects: lighter for both you and me.

I am currently using the 2nd solution. But it would be great:

• either to have a query string parameter to ask only for the result count, to simplify & lighten the 2nd request
• or to add a header or something in a normal API response with the total number of items.

The 2nd solution would be the best, IMO. Moreover, this information could be cached if no select query is present in the request.

What do you think about it ?

@GerkinDev new redis caching is merged and live, should be good to go on this issue 👍

In addition to the new header, I also made slight changes to the caching header shown when the response is served from cache. spacex-api-cache is the new header, with potential values of HIT or MISS
