Limiting the use of JavaScript widgets to specific domains

In the process of developing a webservice that offers Javascript widgets and Ajax calls limited to specific domains, I have explored various options. However, my research has led me to consider using a combination of HTTP-Referer and API Keys for access control. But, I am concerned about the vulnerability of this approach as tools like RefControl can easily bypass it. Are there more robust and secure solutions available for addressing this issue?

Answer №1

REFERER and API keys are essential for ensuring secure requests, given that it is the user's browser initiating the request instead of the server.

Utilizing tools like RefControl is unnecessary in this scenario: While it may prevent an individual user from sending unauthorized requests to your widget, it does not grant a website owner the ability to use the widget without permission.
