Re: [lwip-users] POST issues with different browsers

[tomek wilkxt]

Hi

I had a similar problem with GET, OK in firefox but not in chrome
anymore. This was due to the fact that chromium immediately made two
parallel queries when establishing the connection. My STM32 have smal
RAM and was unable to handle it. Helped decres max content len to 3072
from 8192
#define MBEDTLS_SSL_MAX_CONTENT_LEN 3072 in confg.h
