One thing about writing AJAX calls is that you are limited to calling the same server for security reasons. To work around this issue, I gave this proxy a try and it worked for me and saved me time writing my own.
The follow-up questions I have about this proxy implementations are:
1. It’s only a binary distribution? Not open source?
2. I didn’t see any license information. Is this in public domain?
3. Any potential security risks for this implementation?
Let me know if you know the answers to these questions.
