Sometimes, you may want to know which proxy node is processing your request. There are two ways to do this, each with its own pros and cons.


Method 1: Check your IP with the first request

Send your first request to a service that shows your IP, like:

Then, make your actual request.

Pros:

  • Easy to use with any HTTP client.

  • If the first node isn't available, the proxy will automatically try another one.

Cons:

  • We cannot guarantee that the same node will be used for both the IP check and the next request. If a node change occurs, it will happen seamlessly without any notification to the user.


Method 2: Use the "respond-with" header

To obtain information about the node being used, send a request to our server with the "respond-with" HTTP header in the proxy settings, including one or more of the following parameters:

request_id
uid
conn_type
country
region
city
isp
asn
ip

Example:

curl -x "<your package login>:wifi;[email protected]:9000" --proxy-header 'respond-with: ip,country' -v https://www.cloudflare.com/cdn-cgi/trace

Pros:

  • The exact node from which you received information will be the one that processes your request.

  • You can receive not only basic IP information and connection type but also request_id and node_uid, which you can get only from SOAX.

Cons:

  • It only works with HTTPS requests.

  • There are no automatic retries if the node fails.
