I don't get it.
You have a web server, which accepts connections coming from clients and responds to their requests. There is no such thing as a TCPIP call. I assume you are talking about a TCP connection request. The client connects to the server, the client decides to reconnect or not if connection is lost, and lwIP is in no way related to this (as it is acting as a server, as you said). The client will decide to try to connect forever or give up after n attempts depending on whatever the javascript programmer has put on the javascript code you are serving the client with your webserver when it requests that. What do you want to do on the server ? Would you please define "react" ? There are TCP timers to play around, but if you don't get a connection request from the client... Do you actually have a network traffic capture to see why the client is not sending data or if the server is losing data ? Have you at least debugged the javascript app to see what is going on from its very own point of view ?
