GetMethod.getResponseBodyAsStream() .available() could return content-length

           Summary: GetMethod.getResponseBodyAsStream() .available() could
                    return content-length
           Product: Commons
           Version: 2.0 Final
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: HttpClient

It would be nice if the InputStream returned from
GetMethod.getResponseBodyAsStream() could override the available()
method to return the content-length of the requested URL.  This would
make things like ProgressMonitorInputStream useful for monitoring the
progress of a download.  Here is a code snippet:


/**
 * supply a hard-coded value for available() method.
 */
class FixedInputStream extends FilterInputStream {
  private int contentLength;

  public FixedInputStream(InputStream is,
              int contentLength) {
    super(is);
    this.contentLength = contentLength;
  }

  public int available() throws IOException {
    return contentLength;
  }
} 


Also, somewhat related to this request, could
GetMethod.getResponseContentLength() must be made public?  Is there a
good reason for it to be protected?  I had to extend GetMethod and
implement a public getResponseContentLength() in order to feed that
value to my FixedInputStream.

Thanks for your time.
