Question

I have a situation in which I am a bit confused on how to complete.

Example domains:
http://url1.com
http://url2.com

url1.com has a registration form url2.com has another form.

I need to pass the POST values from url1.com to url2.com without an actual submit happening. On url2.com I need to reconstruct the form with the POST values from url1.com and append hidden input values to the reconstructed form and then submit. I would like to completed this with JavaScript / jQuery if possible.

I would like to note that the url1.com contains a registration form with login and password.

Any advice is greatly appreciated.

Thanks in advance.

Here is how you could post to another URL:

function post_to_url(path, params, method) {
    method = method || "post"; // Set method to post by default, if not specified.

    // The rest of this code assumes you are not using a library.
    // It can be made less wordy if you use one.
    var form = document.createElement("form");
    form.setAttribute("method", method);
    form.setAttribute("action", path);

    for(var key in params) {
        var hiddenField = document.createElement("input");
        hiddenField.setAttribute("type", "hidden");
        hiddenField.setAttribute("name", key);
        hiddenField.setAttribute("value", params[key]);

        form.appendChild(hiddenField);
    }

    document.body.appendChild(form);
    form.submit();
}

There are other solutions there as well.

P.S. Regarding the security question, read here:
Are https URLs encrypted?

Essentially, all the data you pass over secure connections are encrypted, be it GET or POST. And be aware that even if you post data over regular http it could be intercepted by the man in the middle even if it is not visible for the user in the URL.
