Code:

from socket import *
sP = 14000
servSock = socket(AF_INET,SOCK_STREAM)
servSock.bind(('',sP))
servSock.listen(1)

while 1:
  connSock, addr = servSock.accept()
  connSock.send('HTTP/1.0 200 OK\nContent-Type:text/html\nConnection:close\n<html>...</html>')
connSock.close()

When I go to the browser and type in localhost:14000, I get an error 101- ERR_CONNECTION_RESET The connection was reset? Not sure why! What am I doing wrong

    Several bugs, some more severe than others … as @IanWetherbee already noted, you need an empty line before the body. You also should send \r\n not just \n. You should use sendall to avoid short sends. Last, you need to close the connection once you’re done sending.

    Here’s a slightly modified version of the above:

    from socket import *
sP = 14000
servSock = socket(AF_INET,SOCK_STREAM)
servSock.bind(('',sP))
servSock.listen(1)

while 1:
  connSock, addr = servSock.accept()
  connSock.sendall('HTTP/1.0 200 OK\r\nContent-Type:text/html\r\nConnection:close\r\n\r\n<html><head>foo</head></html>\r\n')
  connSock.close()
