socket state = SOCKET_ESTABLISHED

Question

hi, dear developers! i make some device with HTTP - server with W5500. when i connect with telnet to my Server - that’s all OK. but when i connect from browser - i have some trouble. my server send some data, and then close connection. and in the next time browser open new connection, and don’t send any data… it’s bad for me because i have only 7 sockets. thats some trasing data: ###HTTP_process ---socket: 00000 ---Size 00429 - this counter for bytes RX from browser --- no Content Length login.php login page write... write end. HTTP/1.1 200 OK Content-Type: text/html; charset=windows-1251 Connection: close Server: aHata ▒▒▒▒▒▒▒▒▒▒:test ---IP_SATE_CLOSE 00000 ---closing begin ---socket closed socket state 00001 ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ###HTTP_process ---socket: 00000 ---Size 00000 - this counter for bytes RX from browser ---IP_SATE_CLOSE 00000 ---closing begin ---socket closed socket state 00001 how can i stop keep silent from browser? or it’s problems with my code

even if i do disconnect(socketn); close(socketn); it takes many time. browser does not want to shut off. my browser Opera, or Chrome, or Vivaldi. all this browsers keep-alive connection. (i send header Connection: close). In the fire fox all OK.
