javascript - Client keeps requesting file from REST API -


i have audio file stored on server , clients can request these audio files via rest api. observed data requested client , came conclusion whenever play audio again (repeat), new request goes server specific file. there way prevent or cache data locally?

html 

<audio controls="controls" autoplay style="width: 100%">     <source src="https://localhost:8080/api/file" type="audio/mpeg"> </audio>

javascript (node.js in combination express.js) 

router.get('/file', (req, res) => {     let audiofile = path.join(__dirname, 'files/audio-book.mp3');     res.sendfile(audiofile); })

edit

i have local file , file sent rest api. local file request has http code 304: not modified , file rest api request 206: partial content. added max-age , removed last-modified, no result.

headers:

accept-ranges -> bytes cache-control -> public, max-age=3600 connection -> keep-alive content-length -> 7056954 content-type -> audio/mpeg date -> sun, 17 jan 2016 10:16:48 gmt etag -> w/"6bae3a-15195a7f2aa" x-powered-by → express

situation

what happened browser wouldn't cache file in way, shape or form. let tremendous amounts of traffic.

solution

i found this article on stackoverflow requesting files in blobs , letting audio- or video element play it. xhr file server , store in blob , when replay audio, retrieves data cache , can work offline now.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
