I am using SBCL 1.04. I've just upgraded to latest hunchentoot, drakma etc... It happens when I upload a file using POST request. Most of the times the http-request just works and returns the result which I parse and it's meaningful. Occasionally (1 out of 10 times) the http-request returns nil. To verify it, I tested it not from the web, but from the slime propt. It it took me a while to understand why my web app was misbehaving sometimes. For now I put a workaround like (loop for i from 0 to 5 while (not http-request-result) do (setq http-request-result (drakma:http-request ....)) which works. I'd like to know if it's an expected behavior of the http request or is there something I/we could do to fix it?
Thank you, Andrew

Of course not.
or is there something I/we could do to fix it?
I'd need a reproducible test case to say more about it.
I wish I could provide the test case but in this case I log on to the server, it gives the the secure token which I use later to do the file upload. I call the http-request with :method :post, :form-data t, :content-length t. The rest are parameters to the POST. Anyway, I'll keep an eye on it and when I can I'll provide the test case.

Maybe the secure token only has a limited TTL? But, still, Drakma shouldn't simply return NIL.

You could use *HEADER-STREAM* to see what's happening. Or, even better, you could use WireShark to log the whole HTTP traffic. If the problem resurfaces, you'll just have to extract the relevant part.
