Re: [lwip-users] Simultaneous GET requests to HTTP Server

[Antonio Gonga]

Hi Simeon, 

I am not sure but I believe, the server does not send anything because it still 
processing the first request when the others arrive. 

Q: Did you try to use threads in your server ? For example I had developed one 
multi-thread HTTP server using LWIP-1.4 and I was able to have many HTTP 
requests and high rate pings (ping -i 0.2 a.b.c.d), and the server was capable 
of handling my requests.. 
Essentially, for each accept return, you create a new thread to handle that 
request.

Subject: [lwip-users] Simultaneous GET requests to HTTP Server

Hello,

I need some help about the usage of the HTTP Server. My current problem
is the following. I have some WEB pages that use some styles,
JavaScripts, pictures as usual. When I set an option to the WEB Browser
(up to now I use always Firefox) to make only one GET request at a time,
all works without any problems. But by default the simultaneous requests
of the browser are set to 6. In this case, index page is loaded correct,
then the browser generates simultaneous GET requests to read a style and
a JavaScript and at this point the communication brakes - I see that the
HTTP Server stops sending the next frames with the data of the files. It
happens the same if the simultaneous requests are even 2. So it works
only if the requests are following one after another. I suppose that
this is something in my code, or more usual in some settings of the
stack or HTTP Server, but I can't find out what is it. I'm using LWIP
stack V1.4.1. Can you give me an advice what I have to check, please?

Best regards!
