Cookies

Web Unblocker maximizes website unblocking efficiency by using cookies predefined by our team.

Starting on May 10th, 2024, our system will automatically reject any cookies sent by the client to optimize success rates, unless indicated otherwise.

Change preview (Before May 10th)

To facilitate a smooth transition, we offer the option to preview this change. You can assess its impact by sending the x-oxylabs-force-cookies:0 request header, enabling you to make any necessary adjustments beforehand.

Code examples

Change implementation (After May 10th):

In the event that you need to include your own cookies, you can achieve this by incorporating the x-oxylabs-force-cookies:1 request header in your requests. Web Unblocker will merge your custom cookies into the predefined cookies set and then use it to access the website.
