i have client-server app , observed (in local environment i.e. lan ) when close stream connects client server @ 1 end, @ other end observable ( i.e. if in client close stream connects client server, @ other end, @ server, noticeable , reported exception in try-catch block surrounds server-stream code ) . how possible ? client/server send specific code stream closed before closing stream ? applicable in wider networks ( big wans ) ? the bigger question when close stream @ 1 end, can rely on fact @ other end noticed , in consequence close thread , not wait endless recieve data never come due fact that stream closed ? the maximum distance between client , server 700 km ( don't know if plays role mentioned in case ) thanks ! in tcp, connection shutdown procedure involves sending additional datagrams other side, each side notice connection orderly shut down. relying on has 1 major pitfall: in case of unorderly shutdown (e.g. physical disconnect of network cable)

css - Prepend comment to SASS/Compass output -

is there convenient way have sass automatically prepend comment beginning of each css output file? specifically, when using compasss i'd stick brief warning telling designers not edit css directly , point them instructions on getting started compass. use output style of :compressed , strips out comments in input scss/sass file. if there isn't convenient way i'll submit issue/patch. thinking of adding option named :output_prefix takes string prepended output css files. compressed strips out comments. suggest put in property: warning { do-not: "edit file"; } regarding proposed patch, not think use case compelling enough warrant such feature.
