java - Replacing hole punched/STUN UDP socket with TCP socket at runtime -


i have situation used stun establish udp [rtp] connection between 2 clients can stream media 1 packet loss. now, done streaming media , 1 client send other client large file. rather using udp [rtp] send large file, find more convenient, programmer, send file tcp because tcp takes care of re-sending lost packets on behalf. can tell client applications stop using udp connections (say "socket.close(); socket = null;") , open new tcp connections @ same port/address udp connections? work or three-way handshake blocked? there timing or security issue involved? in cases replacing hole punched udp tcp work , in cases not work?

tcp , udp ports different. tcp socket @ port 1000, different communication endpoint udp socket @ port 1000. application span new thread, establish new tcp connection , transfer desired file. udp connection can continue exchange of rtp packets.

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: { ...
