Hi,
sometimes a http transfer uses several packets. So I must know when the
last packet is received to start answering. So far I search
'Content-Length' in the 1st packet and subtract the length of each
packet. This causes problems if the string is not in the 1st packet, or

Hi Bill,
Since you are using Luminary micro with lwIP, I would like to bother you a
little.
I worked on a project that uses a Lminary 8962 ARM Cortex-M3 micro. I also want
to develop web server application based on the demo project enet_io from
Luminary distribution CD-ROM for my project.

I did try to get it to run once but it didn't run as is. I took out the

pressing things to do. I do have the luminary development kit and the web

Thanks guys.
You're right, httpd.c has been created by Luminary. I'll ask them
about this issue.

Hi Daniel,
I think you should post this problem to a forum on Luminary-micro web site.
Luminary will respond for this issue.
I was on a training class from Luminary last year. They taught us the embedded
webserver design which use lwIP TCP/IP for their ARM Cortext-M3 platform.

Which http server are you talking about? The one included with lwIP does
not support CGIs currently!
I guess you are using a server provided by whoever packed lwIP and
provides it for his hardware? Since we don't know the code of that
server, I'm afraid we cannot help you here. (Unless someone
Hi, I want to expose two different problems that are maybe related between them:
1)
With INCLUDE_HTTPD_CGI defined and INCLUDE_HTTPD_SSI undefined, my CGI
handlers are correctly called but, whenever I open a plain html page
with images, the http server freezes. This doesn't happen with html
pages
That makes a lot of sense.
Thanks guys for your help. I'll try out what you suggest.
Daniel.

This fits to your description that you might have missed a packet (from
the wireshark log). So unless you don't have any other problems,
treating pbuf chains correctly will do.
I have a few questions that will help me to understand chaining
As a side note, I hope you are calling the loop below in the
tcpip_thread, not from another application thread, which would violate
lwIP threading.
Aside from that, what Bernhard said is true: the packets are buffer for
retransmission until they are ACKed by the remote side, which cannot

Hi,
I think it is the loop. The code that handles the ACK is not executed
before the loop ends. How is this code called?

What does a pbuf chain look like after it comes back from low_level_input?

Hello,
I'm trying to implement the code below, but it stops in the line sock =
socket(AF_INET, SOCK_DGRAM, 0);
the message is "sys_arch_timeouts: ptask != NULL"
the procedure sequence is:
-lwip_socket (type=0, protocol=100)
-alloc_socket (newcon=0x80173c)
-sys_
Hi,
I switched to 1.3.2 and all seams to work fine now
Thanks

Now all works fine here. It was probably caused by a mix of 1.3.0 and
1.3.2 files.
