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.
