i want to download a attachfile from servlet, but now it only can download file which size is less than 20KB.
i don't know why:( actually i use the InputStream got from the attach Part, but it tell me that the InputStream.available() is 0. when download a big file(about 200KB) it seams that is blocked.
now can help me and give me a answer about the InputStream on NetWork, and why it blocked(just look like)?
