How to Send an array as param in url?

Question

xmlHttp.open( "GET", "/mcd/demo.jssp?array="+arr, false ).

And how to fetch it in jssp? My arr lookes like arr= [3214,2345,84834,4847,83474,3244,234834,........ 30k+ values]

Answer 1

max-length of a URL is 2000 characters, so you can't send 30 thousand array items as a GET request

Send the request as of type post

xhttp.open("POST", "/mcd/demo.jssp", true);
xhttp.send("array="+arr);
