javascript - How to prevent Safari from loading back button cache? -


i've noticed common bug browser button usage on web app hitting button after logout loads cached page user appears logged in (though aren't actually).

i found lot of helpful questions helpful answers , employed fixes folks suggested, including every combination of suggested cache-control options in header:

('cache-control', 'no-cache, no-store, must-revalidate, max-age=0, max-stale=0')

and header works on most browsers, no-cache , no-store, no header options solve on safari.

sure enough, reliable way can find resolve safari use javascript such forces reload:

<script>             window.onpageshow = function(event) {                 if (event.persisted) {                     window.location.reload();                 }             }; </script>

the javascript block above does work, if user doesn't disable javascript via safari -> preferences -> security , subsequently hit button. it's edge case, i'm kind of fascinated such popular browser makes such trivial bug tricky!

if has found way make safari play nice without javascript i'd love hear how. in advance!

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
