Getting HTTP header fields

Testing from command line

To view and test your settings, or restoring an issue, you can run a curl command from your shell prompt and add the option flag -v or i. These flags will run curl in verbose mode and print out the header fields, including the custom error code and message.

curl -v [rest of curl command options]

To see a more compact view with the header fields response only use the -i option for curl:

curl -i [rest of curl command options]

Alternatively, you can use the nc command to get the fields printed to screen:

echo "[tcp nc inputs]" | nc -C -v brd.superproxy.io 33335

nc inputs may include “empty” lines, those are essential for correct testing using nc command

`curl` Command snippet

curl command snippet, with all required zone parameters is available in the Overview tab in Bright Data control panel for the zone you are working on.

Accessing via programming language

Bright Data HTTP header fields can be accessed thru your programming language, as any other HTTP header field.

Accessing via Bright Data’s Proxy REST API

Bright data offers a REST API to access its proxy networks as well as the Unlocker product and our SERP for targeting search engines. The error field names are slightly different , yet the content is identical.

Example response:

"status_code": 407,
"status_message": "Proxy Authentication Required",
"error": "Proxy Authentication Required",
"error_message": "No proxy credentials provided. Please add credentials and try again.",
"error_code": "client_10010"

Error Catalog

HTTP Error 400

When Using the Data center/ISP or gIPs products with the -ip-x.x.x.x targeting flag, the error code 400 can appear in case the IPs under your zone has been refreshed, removed, or simply changed due to system updates

This error typically arises after your BrightData account has been recently suspended. An automatic suspension occurs if your account balance becomes negative. If the suspension extends beyond 24 hours, the static allocated IPs will be released from your account. Upon reactivation, the reallocated IPs may differ from the original ones, thus if the previously allocated IPs are still being targeted - this error is thrown.

Whenever this error appears, you should go to your Bright Data Zones page, and view the updated list of IPs relevant to this zone.
