Espressif ESP32-S2 User Manual

Chapter 2. API Reference
If the web server’s socket closes, it frees up the session context by calling free() on the sess_ctx member.
If you wish to use a custom function for freeing the session context, please specify that here.
bool ignore_sess_ctx_changes
Flag indicating if Session Context changes should be ignored
By default, if you change the sess_ctx in some URI handler, the http server will internally free the
earlier context (if non NULL), after the URI handler returns. If you want to manage the alloca-
tion/reallocation/freeing of sess_ctx yourself, set this flag to true, so that the server will not perform
any checks on it. The context will be cleared by the server (by calling free_ctx or free()) only if the
socket gets closed.
struct httpd_uri
Structure for URI handler.
