javascript - jQuery $.ajaxSetup headers applies to all ajaxRequests even when overwritten -


i have in below parameters ajax calls in <head> of document. (i need ios ajax bug @ https://stackoverflow.com/a/12856562/627473

$.ajaxsetup ({             cache: false,             headers: { "cache-control": "no-cache" }         });

i have service communicating denies cache-control header in way.

so tried below before making ajax request. 

$.ajaxsetup ({ cache: true, headers: { 'invoke-control': 'emvx' } });

the above request still includes "cache-control": "no-cache" header. requirement of service making request prohibits cache-control header being in request (even if blank or has cache value.

my request includes invoke-control (which want); not want cache-control show @ all.

i tried specifying headers in $.post request , still merges headers $.ajaxsetup.

i using jquery v1.11.1. there workaround?

there no way can it.

according jquery documentation of jquery.ajaxsetup,

the settings specified here affect all calls $.ajax or ajax-based derivatives such $.get(). can cause undesirable behaviour since other callers (for example, plugins) may expecting normal default settings. reason recommend against using api. instead, set options explicitly in call or define simple plugin so.

it indicates append header calls.

to prevent this,

you can following

instead of using $.ajaxsetup, try use

$.ajax({    beforesend: function(){      jqxhr.setrequestheader("cache-control","no-cache"); }

to specific requests want

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
