| LimitedServletInputStream | | public class LimitedServletInputStream extends ServletInputStream (Code) | | A LimitedServletInputStream wraps another
ServletInputStream in order to keep track of how many bytes
have been read and detect when the Content-Length limit has been reached.
This is necessary since some servlet containers are slow to notice the end
of stream and cause the client code to hang if it tries to read past it.

| Method Summary | |
| public int | read()
Implement length limitation on top of the read method of
the wrapped ServletInputStream. | | public int | read(byte b, int off, int len)
Implement length limitation on top of the read method of
the wrapped ServletInputStream.
Parameters:
b - destination buffer.
Parameters:
off - offset at which to start storing bytes.
Parameters:
len - maximum number of bytes to read. | | public int | readLine(byte b, int off, int len)
Implement length limitation on top of the readLine method of
the wrapped ServletInputStream.
Parameters:
b - an array of bytes into which data is read.
Parameters:
off - an integer specifying the character at whichthis method begins reading.
Parameters:
len - an integer specifying the maximum number of bytes to read. |

the wrapped ServletInputStream.
Parameters:
b - an array of bytes into which data is read.
