c# - NoBufferSpaceAvailable when sending data to socket -

-

i use on connected socket on server send data client:

iasyncresult asyncres = connectionsocket.beginsend(data, 0, length, socketflags.none,       out error, new asynccallback(senddatadone), signalwhendatasent);

as seems, when there slow internet connection between server , client receive exception description this: nobufferspaceavailable

what error mean ? internal os buffer socket connectionsocket full ? means make work. context appears in http proxy server. might indicate, i suppose, rate @ data coming origin server higher rate server can handle proxy client. how deal ?

i using tcp.

the way fix problem correlate way 1 reads 1 socket speed 1 writes other socket because if no buffering cannot write socket @ higher speed client connected @ end can read.

you 1 uses synchronous sockets problem not appear because block long operation still pending not case async calls.
