Hi,

The easiest way to do auto fill is to use LoadRequest to load a HTTP POST request, which is what occurs after user presses the login button. Here is a more detailed step by step of what happens:

1. The browser loads the login page;
2. The user fills in the user name and password box;
3. The user clicks "login" button;
4. The browser assembles a HTTP POST request, form data (that contains user name and password) are attached to this request;
5. The browser send this request to the server;

Instead of start simulating from step 2, you can start simulating from step 4. This would bypass all the JavaScript code.

It is possible that the web page intentionally includes some additional data beside user name and password in step 4 for security purpose. For example, they can include a security token that the server generated at step 1. Obviously in such cases you won't be able to skip step 1. In that case you will have to dig into the script code to find out what will make the server happy. You can use a traffic monitor such fiddler to compare the final login request sent when you use auto fill against the request sent when user clicks the button manually and then start from there.

Thanks!
