javascript - Websocket prevent data frame loss -


we using websocket send user activity events such clicks,mousemove,scroll,input , ... along it, send html dom snapshot too. average size of html snapshot around ~300 kb. in cases, html snapshot has not reaching our servers. below few scenarios.

  2. while in slow network

we tried sending remaining events on beforeunload event not working.

is there anyway solve problem?

as far know there no way solve this.

you can use beforeunload event gain time, cannot block until data sent asynchronously.
