Use curl to send a static xml file using url encoding to a web page using pos
Hi I am try to use curl to send a static xml file using url encoding to a web page using post. This has to go through a particular port on our firewall as well. This is my first exposure to curl and am not having much success, so any help you can supply, or point me in the right direction would be greatly appreciated.
I also have a quick question concerning post; does the post command record the originating address? The reason I am asking is that the web page I am sending the xml to requires that the connection be made over the internet from one machine's ip to the other machine's ip over an open port on our firewall. We are configured with an open port on the fire wall but for security reasons the ip address is on firewall as well, this is were traffic is being directed to and from both machines.
When I send the post command from the the originating machine would the web page that receives this become confused, as it is not coming from the ip address it is expecting?
thank you for your time.

curlopt_postfieldsize
CURLOPT_POSTFIELDSIZE(3) curl_easy_setopt options CURLOPT_POSTFIELDSIZE(3)
NAME
CURLOPT_POSTFIELDSIZE - size of POST data pointed to
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE, long size);
DESCRIPTION
If you want to post data to the server without having libcurl do a strlen() to measure the data size, this option must be used. When this
option is used you can post fully binary data, which otherwise is likely to fail. If this size is set to -1, the library will use strlen()
to get the size.
If you post more than 2GB, use CURLOPT_POSTFIELDSIZE_LARGE(3).
DEFAULT
-1
PROTOCOLS
HTTP
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
const char *data = "data to send";
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
/* size of the POST data */
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, (long) strlen(data));
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
curl_easy_perform(curl);
}
AVAILABILITY
Along with HTTP
RETURN VALUE
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
