Difference between CURL and HTTP POST

[pranvkavi]

For a particular SMS application, I am supposed to send the following XML content to an external URL.

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE MESSAGE SYSTEM "http://127.0.0.1/psms/dtd/message.dtd" >
<MESSAGE>
<USER USERNAME="mycompany" PASSWORD="mycompany"/>
<SMS UDH="0" CODING="1" TEXT="hey this is a real test" PROPERTY="" ID="1"
DLR="0" VALIDITY="0">
<ADDRESS FROM="9812345678" TO="919812345678" SEQ="1" TAG="some
client side random data" />
</SMS>
</MESSAGE>

 

When I send it through a simple HTTP POST(form submit), it seems to work fine. The recipient(s) recieves the message. But if I replicate the same procedure through CURL, the external url gives that the XML send does not conform to DTD. The XML content is urlencoded before being sent through CURL.

 

Is there a difference between a CURL POST and a normal HTTP POST that can cause the above problem?? I could really use some help....

Please post the code you're using.
