This is my first time building a simple site with a shopping cart. The cart is powered by javascript and functions properly. I am using authorize.net to process credit card transactions and they have provided me with a sample code file to connect with them. The file is of extension .jsp.

For reference, the website is: www.comfortcuisineonline.com

The final page to submit checkout is checkout.html and contains a form to collect the required data to be passed to the .jsp page.

My form looks something like this:
<form action="https://www.comfortcuisineonline.com/scripts/post.jsp" method="post" name="checkoutform">
...form contents...
<input type="submit" value="proceed to payment">
</form>

I have run into all kinds of IIS errors and am running on a linux based server through godaddy.

I am wondering if I can post to the .jsp file without navigating to it or running into the error:
"The requested method POST is not allowed for the URL /scripts/post.jsp.
Apache/1.3.33 Server at www.comfortcuisineonline.com Port 443"

Here is code from the SAMPLE .jsp file (mine has my info in it)
