Headers & Cookies

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

Custom headers

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. Web Unblocker will merge your custom headers into the predefined headers set and then use it to access the website.

Code examples

curl -k -v -x https://unblock.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
'https://ip.oxylabs.io/headers' \
-H 'x-oxylabs-force-headers: 1' \
-H 'Accept-Language: en-GB' \
-H 'Your-Header-Name: interesting header content'

import requests

# Use your Web Unblocker credentials here.
USERNAME, PASSWORD = 'YOUR_USERNAME', 'YOUR_PASSWORD'

# Define proxy dict.
proxies = {
  'http': f'http://{USERNAME}:{PASSWORD}@unblock.oxylabs.io:60000',
  'https': f'https://{USERNAME}:{PASSWORD}@unblock.oxylabs.io:60000',
}

headers = {
    'x-oxylabs-force-headers': '1',
    'Accept-Language': 'en-GB',
    'Your-Header-Name': 'interesting header content'
}

response = requests.get(
    'https://ip.oxylabs.io/headers',
    verify=False,  # It is required to ignore certificate
    proxies=proxies,
    headers=headers,
)

# Print result page to stdout
print(response.text)

# Save returned HTML to result.html file
with open('result.html', 'w') as f:
    f.write(response.text)

import fetch from 'node-fetch';
import { HttpsProxyAgent } from 'https-proxy-agent';

const username = 'YOUR_USERNAME';
const password = 'YOUR_PASSWORD';

const agent = new HttpsProxyAgent(
  `https://${username}:${password}@unblock.oxylabs.io:60000`
);

// We recommend accepting our certificate instead of allowing insecure (http) traffic
process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0;

const headers = {
   'x-oxylabs-force-headers': '1',
   'Accept-Language': 'en-GB',
   'Your-Header-Name': 'interesting header content'
}

const response = await fetch('https://ip.oxylabs.io/headers', {
  method: 'get',
  headers: headers,

});

console.log(await response.text());
