config HTTPD_MAX_REQ_HDR_LEN
int "Max HTTP Request Header Length"
default 512
help
This sets the maximum supported size of headers section in HTTP request packet to be processed by the
server
config HTTPD_MAX_URI_LEN
int "Max HTTP URI Length"
default 512
help
This sets the maximum supported size of HTTP request URI to be processed by the server
config HTTPD_ERR_RESP_NO_DELAY
bool "Use TCP_NODELAY socket option when sending HTTP error responses"
default y
help
Using TCP_NODEALY socket option ensures that HTTP error response reaches the client before the
underlying socket is closed. Please note that turning this off may cause multiple test failures
config HTTPD_PURGE_BUF_LEN
int "Length of temporary buffer for purging data"
default 32
help
This sets the size of the temporary buffer used to receive and discard any remaining data that is
received from the HTTP client in the request, but not processed as part of the server HTTP request
handler.
If the remaining data is larger than the available buffer size, the buffer will be filled in multiple
iterations. The buffer should be small enough to fit on the stack, but large enough to avoid excessive
iterations.
config HTTPD_LOG_PURGE_DATA
bool "Log purged content data at Debug level"
default n
help
Enabling this will log discarded binary HTTP request data at Debug level.
For large content data this may not be desirable as it will clutter the log.
config HTTPD_WS_SUPPORT
bool "WebSocket server support"
default n
help
This sets the WebSocket server support.
config HTTPD_QUEUE_WORK_BLOCKING
bool "httpd_queue_work as blocking API"
help
This makes httpd_queue_work() API to wait until a message space is available on UDP control socket.
It internally uses a counting semaphore with count set to `LWIP_UDP_RECVMBOX_SIZE` to achieve this.
This config will slightly change API behavior to block until message gets delivered on control socket.
