Examples of sunlabs.brazil.util.http.HttpInputStream

sunlabs.brazil.util.http.HttpInputStream
This class is an input stream that provides added methods that are of help when reading the result of an HTTP request. By setting up this input stream, the user can conveniently read lines of text and copy the contents of an input stream to an output stream.
The underlying assumption of this class is that when reading the result of an HTTP request, each byte in the input stream represents an 8-bit ASCII character, and as such, it is perfectly valid to treat each byte as a character. Locale-based conversion is not appropriate in this circumstance, so the java.io.BufferedReader.readLine method should not be used. @author Colin Stevens (colin.stevens@sun.com) @version 2.2
