External Shipping Calculators
The following shipping modules all need cURL which is not installed on this server, you may need to contact your web hosting provider to get it set up.
I am trying to configure the usps settings to calculate automatic postage according the zip code.
I figured that I had to activate the cURL in the PHP 5.3 php.ini file in my server.
I opened the php.ini and activated the extension=php_curl.dll and extension=php_curl.dll. Also I copied the libeay32.dll and ssleay32.dll files to C:\windows\system32 and I restart the server.
I edit the user name and password in the shipping modules>USPS>Login page and I pressed the calculate buttton for the shipping.
The result was a panic.
The errors was all over the screen and long.

In the end I cleard the shopping cart and I tried to add another item when this error occur.
The specified CGI application misbehaved by not returning a complete set of HTTP headers.
