Stipe,

Thanks for the response, BUT this is not exactly what I am asking for. I
already implemented the scenario you describe (could not fetch). In my
scenario the HTTP request is delivered to the HTTP server, BUT BEFORE the
HTTP server delivers the expected response to kannel, the connection goes
down. 

who brings the connection down? Is it because kannel doesnt wait long enough or because the server closes down.
It can also be a proxy server or firewall in the middle which cuts...

So kannel thinks that everything is ok (it delivered the http request
sucessfully), BUT it gets no response-SMS and the user receives nothing in
his mobile (as the connection is down). 
Any further ideas ?

Thanks in advance

Subject: Re: Connection failed ?


An SMS is sent from a user's mobile phone to kannel. Kannel identifies the
specific service, and a URL is requested via the GET-method. Kannel
expects
the response from the URL, BUT, the connection between kannel and HTTP
Server is lost, BEFORE kannel receives the response SMS, that is supposed
to
return as an answer to user. Is there any way to handle this situation,
e.g.
sending an SMS to the user after waiting for 2 or 3 minutes and not having
a
response from the HTTP server? I understand that kannel can handle some
situations like requestfailed, couldnotfetch, requestfailed, emptymessage,
but I don't think that can handle the above scenario. Am I correct?
Do you have any ideas ? Waiting for your response. Thanks in advance

yes, Kannel (or specifically the smsbox) can handle this. smsbox can
have an HTTP request queueing mechanism where you can have several
tries to deliver the HTTP request to the HTTP server. Please see
user's guide for configuration directives.

Now as smsbox will tried all HTTP GETs as failed, when no answer is
given, it will retry to N times that you can configure. If it fails
for all N times, then the smsbox will pass a "could not fetch" message
to the user via bearerbox.
