Binary data 0x01 0x02 0x03 is 3 bytes - in URL encoding it would be "%01%02%03" 9 bytes. > I was wondering what the purpose of EntityUtils is there, if I could just use getContent(). > > If it matters, I am reading the stream twice, once to check the total > size of the zip files for a progress bar and once to extract them. > Should this mean it's much more efficient to convert the HttpEntity > to a byte[] array first? Should using getContent() as the input to > the zip stream make the second read slower but use much less memory? You will need to find it in the documentation or do a test. But my guess is that getContent() will work the first time and fail the second time. Meaning that toByteArray may make sense if you really need that progress bar. Question: can't you just use HTTP content length instead?? Arne
