javascript - Custom Tile Source Multiple Image Hosts? -


in experimenting custom tile source in openseadragon, wondering if there way cycle multiple image hosts, improve async way in browser retrieves resources?

in 

gettileurl: function(level, x, y){   return "imagecdn1.example.com/" +      level + "/" + x + "_" + "y" + ".png"

..can put %d or sort of cycling value (of '1' in example) following round-robin set of calls tiles?

example sequence:

imagecdn1.example.com imagecdn2.example.com imagecdn3.example.com

is possible?

as follow-up if not possible, improve performance anyway in browser, in should doing @ url level?

this not possible can in gettileurl method:

var inc = 0; gettileurl: function(level, x, y){   inc++;   inc = inc % 3 + 1; //number of cdn have   return "imagecdn" + inc + ".example.com/" +      level + "/" + x + "_" + "y" + ".png"

i doubt beneficial though.

one disadvantage can think of if tile cached @ 1 url, redownloaded anyway if gettileurl return different url.
