- buffer
- a buffer holding the line to inspect
- cursor
- the cursor at which to check for a protocol version, or negative for "end of line". Whether the check tolerates whitespace before or after the protocol version is implementation dependent.

Checks whether there likely is a protocol version in a line. This method implements a heuristic to check for a likely protocol version specification. It does not guarantee that ILineParser.ParseProtocolVersion(Org.Apache.Http.Util.CharArrayBuffer, Org.Apache.Http.Message.ParserCursor) would not detect a parse error. This can be used to detect garbage lines before a request or status line.
