[Noam Weissman]

Hi,

I am not familiar with netconn API but I will try..

Every browser implements the protocol a bit differently. The data fields in the 
HTTP may not be
In the same order and sometimes (IE) are very long… That leads to problems when 
your code
Is very optimized and unexpected.

I found that on the hard way when I was working on HTTP myself. Use Wireshark 
and maybe
debug printouts in your own code to see what is the difference.

I suggest using the RAW API HTTP server as it is used by many programmers.

BR,
Noam.

I am using HTTP server example using the netconn API,

Last time I tested those two browsers, chrome used more simultaneous 
connections to my server than firefox. That explains the difference. Your 
server shouldn't crash though. That's a bug in your port or application and you 
should fix it :-)

Hi Mohamed,

Part of the LwIP contributions you have working HTTP servers. Have you used one 
of these or
created something of your own ?

What is the API that you are using: RAW, Netcon or Socket ?


BR,
Noam.

hello,
I'm cuurently using SmartFusion2 SoC and LwIP ontop of FreeRTOS,
I implemented a basic HTTP server over TCP, the problem I am facing is
when reloading a tab in chrome or adding new one the server crashs. Note
that the server runs well with firefox.
Any help please ?
Thank you in advance
