Multiple parallel subrequests

[bengrimm]

Right now location capture is done in the background, but you're limited to issuing one request at a time. If you need to pull data from multiple sources, your page is as slow as the sum of all subrequests, but would be reduced to just the slowest if they could be issued in parallel.

If a table were passed to location.capture like this, then it would respond with an identical table of res objects.

res = ngx.location.capture({ "http://this/...", "http://that/...", "http://..." })
ngx.print( res[0].body, res[1].body, res[2].body )

Or it may be easier to use a separate function (e.g. capture_multi).

Right, it's been on our TODO list :) There indeed will be a .capture_multi method. Do you have the tuits to provide a patch? ;)

Thanks!

[bengrimm]

Perhaps. I'll see what I can do!

I've implemented ngx.location.capture_multi() in git HEAD. See README (and related test cases in the t/027-multi-capture.t file) for the documentation of this new function. Please try it out to see if it works for you ;)

Enjoy!
