I think this question is a protocol problem more than anything. A quick bit of searching "http server abort upload" reveals what to do:
https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.14 https://groups.google.com/forum/#!topic/golang-nuts/agB-n6V7UsQ There is also this informative SO post: https://stackoverflow.com/questions/18367824/how-to-cancel-http-upload-from-data-events#18370751 So: Respond with "413 Request Entity Too Large" as soon as you detect it is too big, and use w.Header().Set("Connection", "close") to tell the client to close the connection. Not sure how to tell the server to close the connection. On HTTP1 you can at least Hijack the connection and Close it. On HTTP2 I don't see an obvious way. https://tip.golang.org/pkg/net/http/#Hijacker Note that this does result in a non-ideal UX unless you do the upload with AJAX, but this looks like an issue with the browsers, according to the above SO post. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
