Member Enumeration Documentation

anonymous enum [protected]

Enumerator:

MAX_HEADER_SIZE	The handler assumes that the first 2048 bytes of a server response contains the header
MTU	set the MAX_TRANSMISSION_UNIT (MTU) = BUFSIZ as defined by OS

Definition at line 69 of file HTTP_Handler.h.

  {
    /// The handler assumes that the first 2048 bytes of a server response
    /// contains the header
    MAX_HEADER_SIZE = 2048,

    /// set the MAX_TRANSMISSION_UNIT (MTU) = BUFSIZ as defined by OS
