I don't have a rar archive reader to hand, sorry.  Can you avoid
packaging them?  Just attaching the files to your email should be fine
as they shouldn't be very big.

That's odd.

I guess my best suggestion would be to go back to the "lwip-http"
example that you based this code on (can you show us the code that you
started from, it's not clear from your email which example you meant)
and check that it works.  Then change it to what you want to do a little
at a time and check at each stage that it still works.  This should
quickly show up what you're doing wrong.
