[lwip-users] HTTPD Web server and Google Chrome problem

[Info]

Hi

I'm using the lwIP (1.4.1) with a web server (httpd from the 
httpserver_raw of the corresponding contrib package) in my embedded 
application. Since a few month I'm seeing a problem with browsers on 
Windows OS (version seems doesn't matter) using the "Chrome engine" 
(Edge, Vivaldi an of course Chrome itself) if accessing the web server 
(Firefox does not have the problem). On Linux there are no problems at 
all (Vivaldi for example does not have this problem). The embedded 
application itself uses FreeRTOS.

Problem description:
The browser loads web content from the web server and starts to 
communicate periodically with the web server. With browsers using the 
"Chrome engine" the communication stops after a view minutes. With 
Firefox all works fine (for hours or days). After reload of the web 
content in the browser the whole starts again, that means the web server 
and the lwIP are NOT crashing and running until the next problem of the 
communication.

I have attached a Wireshark capture, which shows the stop of the 
communication with web server.

Does someone have an idea why this happens ? Some help would be apprenticed.

P.S.: I know the lwIP version is an old one. I have planned to update it 
to the newest version, but not at this time if it is not absolutely 
required.

Thank you very much,
Roland
