** Author: Joshua Teitelbaum
** File: httppost.cpp/h
** License: see jnetlib.h
** Usage:
**   1. Create a JNL_HTTPPost object, optionally specifying a JNL_AsyncDNS
**      object to use (or NULL for none, or JNL_CONNECTION_AUTODNS for auto),
**      and the receive buffer size, and a string specifying proxy (or NULL 
**      for none). See note on proxy string below.
**   2. call addheader() to add whatever headers you want. It is recommended to
**      add at least the following two:
**        addheader("User-Agent:MyApp (Mozilla)");
*///      addheader("Accept:*/*");
/*  Joshua Teitelbaum 1/15/2006
**   2.5 call addfield to add field items to your POST
**   2.9 call addfile to add file items to your POST
*/
/*         ( the comment weirdness is there so I Can do the star-slash :)
**   3. Call connect() with the URL you wish to Post (see URL string note below)
**   4. Call run() once in a while, checking to see if it returns -1 
**      (if it does return -1, call geterrorstr() to see what the error is).
**      (if it returns 1, no big deal, the connection has closed).
**   5. While you're at it, you can call bytes_available() to see if any data
**      from the http stream is available, or getheader() to see if any headers
**      are available, or getreply() to see the HTTP reply, or getallheaders() 
**      to get a double null terminated, null delimited list of headers returned.
**   6. If you want to read from the stream, call get_bytes (which returns how much
**      was actually read).
**   7. content_length() is a helper function that uses getheader() to check the
**      content-length header.
**   8. Delete ye' ol' object when done.
**
** Proxy String:
**   should be in the format of host:port, or user@host:port, or 
**   user:password@host:port. if port is not specified, 80 is assumed.
** URL String:
**   should be in the format of http://user:pass@host:port/requestwhatever
**   note that user, pass, port, and /requestwhatever are all optional :)
**   note that also, http:// is really not important. if you do poo://
**   or even leave out the http:// altogether, it will still work.
