Well, urlencoding is not right, still. In your URL ytou need to encode /, &
and ?. Don't need to encode = or 8. But I think you want to encode &type=%d.
That should be %26type=%%d
So is this working or not? What do you mean by 3 parmaters, not 2? This is
the dlr-url you send in your XML.

No worries, I spent good few hours myself to find it.
I actually tried to encode/ url-escape the dlr-url but the result were
similar:
Here the logs:
first case I escaped the entire URL
2010-02-17 19:33:16 [1593] [9] DEBUG: Parsing URL
`http://localhost/delivery-report.php?send_history_id=13853213%26to_number%3D353870632346%26type%3D%25d':
second case I escaped just & -> %26
2010-02-17 19:56:45 [1593] [9] DEBUG: Parsing URL
`http://localhost/delivery-report.php?send_history_id=13853215%26to_number=353870632346%26type=8'
Basically what is happening is that instead of GET sending three
parameters is just sending one string and the & are represented by
%26.

Hi,
I used both iptraf and a custom script to dump the request and I
verified what I am sending (the XML in the previous email is from
dumping the request I am sending).
However, I agree with you and I trust the logs and even the logs say
the same thing.
The GET you see there is the GET generated by Kannel toward my
endpoint to confirm the delivery.
I found this bit in the log and it might be useful: The url is not
un-escaped (& appears there)

I am attaching the log which show step by step all the sequence from
when my XML-POST request is received to when the delivery is
generated.
Do I need to encode the elements is some way ?

Hi,
Please verify what you are sending. Use tcpdump or another sniffer. From
SMS logs you don't send *any* POSTs, just a GET and an incomplete one at
that. If it comes to what I trust more, logs or your sayings, I'll go
with
the logs, anythime.

Subject: Re: XML Post and dlr-url
Hi All,
Sorry I think I wasn't really precise.
I am using XML-POST to send sms through cgi-bin/sendmessage. Basically
what I do is very simple. I build the XML request into a string
and the I send it using an HTTP/POST. To write the XML request I am using
a Perl library (XML::Writer) which produces a valid XML.
When I post I specify the Content-type 'text/xml'.
res = $self->{'UA'}->post( $service_url, 'Content-type' => 'text/xml',
'Content' => $xml_str);
Everything works messages are processed and sent correctly and the
content
of the message is escaped and un-escaped correctly. There is only one
issue
with the delivery report.
The problem is that one of the element of the XML-POST
http://www.kannel.org/download/1.4.3/userguide-1.4.3/userguide.html#POSTXML
is the url to acknowledge the delivery <dlr-url> </dlr-url>.
This url in plain text (non XML or HTML encoded) is
http://localhost/delivery-report.php?send_history_id=xxxxx&to_number=xxxxx&type=%d
When XML::Writer writes the element <dlr-url> it rightly coverts & to
&. However, Kannel doesn't seem to un-escape the character and as a
result the url which is used by the smsbox to report the delivery is
wrong
because the & is still &
Below an example of xml which I send to kannel:
<?xml version="1.0" encoding="UTF-8"?>
<message>
<submit>
<da><number>353870xxxxx</number></da>
<oa><number>35387xxxxxx</number></oa

<dlr-mask>31</dlr-mask>
<dlr-url>http://localhost/delivery-report.php?send_history_id=13853217&to_number=353870xxxxx6&type=%d</dlr-url></statusrequest>
<!-- request from application to Kannel -->
