javascript - Can I use the HTTP range header to load partial files "on purpose"? -

-

i'm playing around http range header (specs).

from understand can set byte ranges of files ala

0-199/2000 200-499/2000 500-799/2000 etc

question:
want access ranges of file, possible specify these ranges , work "incomplete" data received? i'm playing around filtering large log file, i'm curious if work.

thanks inputs!

you right link posted in comment best approche. question sounded interesting tried out. did it, here snippet(for other may come looking)

var xmlhttp=new xmlhttprequest(); xmlhttp.open("get","data.dat",false); xmlhttp.setrequestheader("range", "bytes=100-200"); xmlhttp.send(); console.info(xmlhttp); //--> returns partial content // tested on win7 chrome 46+

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
