Headers
Web Unblocker maximizes website unblocking efficiency by utilizing predefined headers. Our system automatically filters out client-sent headers to enhance success rates.
If you require the use of your own headers, you can do so by adding the
x-oxylabs-force-headers: 1 header into your requests. This feature allows for the inclusion of standard parameters like Accept-Language, as well as custom headers tailored to specific targets. However, certain custom headers are always rejected, you can find them in this list.cURL
