I was wandering if there is a way to modify FetchURL so that it accepts a maximum number of lines / bytes / specific characters to be read. E.g. FetchURL[..., MaxNumberOfSeparators -> 10, Separators ->"\n"] might stop reading from the url when 10 "\n" have been read. I do not master Java http support libraries enough to do this myself, but is some cases I would have found this functionality useful.
