javascript - How to stop iteration on error | Node.js and MongoDB -


got little problem here that's taking me long solve. might idiot because feel simple problem cant wrap head around it. here's code: 

 get_online = function (err, result) {         if (err) {             return next(err);         }         streamers_size = result.length;         result.map(             function (entry) {                 curl.get                     .to('https://api.twitch.tv/kraken/streams/' + entry.uname)                     .then(update_streamers);             }         );     },      update_streamers = function (err, result) {         var clean;         if (err) {             return next(err);         }         if (result.stream) {             db.collection('streamers').update({                 _id: result.stream.channel._id             }, {                 $set: {                     stream_preview: result.stream.preview.large,                     viewers: result.stream.viewers                 }             }, send_response);         }         else {             clean = result._links.channel.substring(result._links.channel.length, 38);             db.collection('streamers').update({                 uname: clean             }, {                 $set: {                     stream_preview: 'offline',                     viewers: 0                 }             }, send_response);         }     },

what's happening everytime failed request api fires update_streamers callback , triggers if(err), it's going send headers back: return next(err), if failed requests consecutive? therefore it'll send headers repetitively until error says can't send headers set blah blah. more of logical question more anything. question is, how stop iteration (as mentioned in title). appreciated.

create variable errorcount , initialize 0. whenever error, increase it. if 5, stop trying. if there success, set errorcount 0.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
