This is the code i am using to build swf file. I am not able to log in. I need to embed this form on my Salesforce site.

Whats Your Salesforce server instance? You can check it by logging to Salesforce via web browser and it will be presented in the URL just before salesforce.com. Example:

cs7.salesforce.com

Then it might be used in Your server URL. Is it ap1 in Your case?
