Overview

The HTTP Session API provides functions for managing HTTP session. Using the HTTP Session, you can implement features that allow the users of your application to:

  • Create / Delete HTTP session
  • Get activated transaction count
  • Manage redirection

Functions

int http_session_create (http_session_mode_e mode, http_session_h *http_session)
 Creates the HTTP session handle.
int http_session_destroy (http_session_h http_session)
 Destroys the HTTP session handle.
int http_session_open_transaction (http_session_h http_session, http_method_e method, http_transaction_h *http_transaction)
 Opens HTTP transaction from the HTTP Session.
int http_session_set_auto_redirection (http_session_h http_session, bool auto_redirection)
 Sets the value to redirect the HTTP request automatically.
int http_session_get_auto_redirection (http_session_h http_session, bool *auto_redirect)
 Gets the auto redirection for the HTTP request.
int http_session_get_active_transaction_count (http_session_h http_session, int *active_transaction_count)
 Gets the number of active transactions in the current session.
int http_session_get_max_transaction_count (http_session_h http_session, int *transaction_count)
 Gets the maximum number of transactions for the current session.
int http_session_destroy_all_transactions (http_session_h http_session)
 Destroys all transactions.
