You're not going to be able to use a certificate or HTTP in this situation then. The only other thing I can think of is to encrypt your data with the crypto API, but you'd have to be able to unencrypt it on the client side then, and IE doesn't understand it, so this wouldn't meet your requirements.

>>You need to do two things:
>>
>>1. Change the URL you use to use HTTPS instead of HTTP
>>2. Get a certificate from a company like Thawte (www.thawte.com). Certificates are not free, and must be installed on your server. They are issued for a specific company and web site.
