Default header receive buffer size CONFIG_HTTPD_MAX_REQ_HDR_LEN=512 too small #52
Description
The default in build for the sdkconfig configuration parameter is:
CONFIG_HTTPD_MAX_REQ_HDR_LEN=512 (bytes).
On Google Chrome latest version running on MacOS on the latest Catalina OS:
using Wireshark trace - shows the "post" header is 554 bytes long (not incl. CR/LF)
It needs to be set at least 768 bytes, but 1024 would be better.
