I'm starting to use Drakma in a program of mine, and it seems to work fine for me except in one strange case. I was trying to retrieve a page, with (drakma:http-request "http://cesa.iust.ac.ir/"), that I got "Lisp connection closed unexpectedly: exited abnormally with code 256".
I set *header-stream* to see what's happening. This is the result:
GET / HTTP/1.1 Host: cesa.iust.ac.ir User-Agent: Drakma/0.7.0 (SBCL 1.0.3; Linux; 2.6.20-15-generic; http://weitz.de/drakma/) Accept: */* Connection: close

Other web pages I have tested work fine, but this is the one page I'm going to work with. Any ideas? Thanks.

That call works for me on LispWorks.
However, I've had issues with printing debugging output in my environment. I use SLIME and LispWorks and I can get into situations where I print characters to the repl/interaction buffer and that kills my LispWorks image.
So, can we have a little more detail? How are you running sbcl? Is it inside SLIME? Are you trying to print some of the data out to your screen? If so, can you try
(length (drakma:http-request "http://cesa.iust.ac.ir/"))
and see if that works?
For me on LispWorks I get:
(length (drakma:http-request "http://cesa.iust.ac.ir/")) => 71253
When I print out the data, I get utf-8 data in a language I can't read (perhaps Farsi, but I really have no idea!).
Cheers, Chris Dean

As Chris already said, this looks very much like a SLIME issue. Actually, I'd be willing to bet that it is one... :)
Works fine for me with LispWorks on Windows, but the page contains a lot characters I don't know - maybe Arabic.
HTH, Edi.
I am sorry, I should have included more details. Yes, I use SLIME, and you're right. I tried it from SBCL repl and it worked. Actually, it seems when SLIME tries to print the result it runs into problem. Maybe, Persian text causes this problem. Anyway, thanks for you replies. Next time, I'll try to do more tests before posting here.

You may find

(besides Slime's docs) useful for configuring a Unicode-friendly Emacs/Slime/Lisp environment.
