HttpHeader is now capable to handle both plain HTTP requests or also SCGI request - they simply get 'translated' and after parsing the content of HttpHeader is same as if request was direct HTTP.
The heuristics is simple: If HttpHeader::Read founds the first character of request to be digit, it considers it SCGI.
This way we have unqiue feature as servers based on HttpHeader will be able to process both HTTP and SCGI without configuration changes
