This often allows the serverto respond before we start sending data accross the wire. If the write forsome reason fails in a bad way then we try again, waiting a little bit longerthis time as this may give the server enough time to think.The default wait periods are 2000ms for the first wait and 3000ms if thatfails. These are rather conservative values but can be changed by using thesefunctions. The second try value must be larger (or equal) to the first tryvalue and the first try value must be larger than 20 ms.*/extern BOOL HTTP_setBodyWriteDelay (ms_t first_try, ms_t second_try);extern void HTTP_bodyWriteDelay (ms_t * first_try, ms_t * second_try);/*(  HTTP Event Handler)The event handler is the actual HTTP client state machine taking care ofthe communication.*/extern HTProtCallback HTLoadHTTP;extern HTConverter HTTPStatus_new;#endif /* HTTP_H *//*    @(#) $Id: HTTP.html,v 2.39 1998/11/19 17:03:24 frystyk Exp $*/
