How do I configure a proxy in a browser, client, or application?
Every setup uses the same core values: protocol, host, port, and authentication. Enter them in the target tool, then independently verify the egress IP and target region. Menu locations may change between versions, but the parameter model remains the same.
Quick answer
Obtain the protocol, host, port, and authentication data from the current proxy list or extraction result, then map those values to the tool's proxy settings. Save the configuration, verify the egress IP and region, and only then run the real workload. Menu locations change between versions, but this parameter model and test order remain stable.
Prepare the configuration
Collect the complete parameter set before opening the target tool.
- 01
Confirm the product and session model
Decide whether the workload needs fixed egress or rotation, the target region, and whether login state must persist.
- 02
Confirm protocol support in the tool
Check whether the tool supports HTTP, SOCKS5, or the system proxy, and do not place one protocol endpoint in another protocol field.
- 03
Prepare the host, port, and authentication
Copy the values from the current proxy list or extraction result. For allowlisting, add the runtime device public egress IP first.
- 04
Choose the configuration scope
Decide whether the proxy applies to one browser profile, a client, the operating system, or a specific application.
Configure by tool type
Browsers, clients, systems, and code use the same core values.
Standard browser
Use built-in proxy settings, a reviewed extension, or the system proxy, then confirm that the target browser traffic is in scope.
Avoid enabling multiple proxy layers at once
Antidetect browser
Enter the values in the relevant profile proxy settings, save, and verify with the built-in test or an independent detection page.
Verify egress and region for every relevant profile
Proxy client
Create a node or profile, select the protocol, enter the endpoint and authentication, and choose which applications or rules use it.
Test globally first, then narrow routing rules
System proxy
Enter the supported proxy type in the operating system network settings, remembering that not every application follows them.
Verify the actual egress of each critical application
API and application code
Use the API to obtain or manage proxies, then pass the proxy endpoint to the network library. Keep API and proxy authentication separate.
Keep keys in secure server-side configuration
Map each parameter
Labels vary between interfaces, but the fields map consistently.
| Common field | Meaning | Common mistake |
|---|---|---|
| Type / Protocol | MeaningSelect HTTP, SOCKS5, or another protocol supported by the current endpoint. | Common mistakeChoosing by the target URL scheme instead of the proxy endpoint and tool capability. |
| Host / Server | MeaningA split-field UI normally expects only the proxy host or IP. If a library explicitly asks for a proxy URL, follow its complete URL format. | Common mistakeUsing an extraction API URL as the proxy endpoint, or pasting a complete URL without checking the expected field format. |
| Port | MeaningThe connection port paired with the selected protocol and endpoint. | Common mistakeUsing a port from another protocol, another node, or an expired record. |
| Username / Password | MeaningProxy credentials used for username/password authentication; allowlisting may not need them. | Common mistakeEntering site credentials or an API key, or leaving fields empty before allowlisting is active. |
Verify and troubleshoot
Validate the proxy endpoint before testing the target workflow.
After saving the configuration, verify it in this order:
- Use a simple detection target to confirm that a request completes through the proxy.
- Check that the detected egress IP and country or city match the selected resource.
- Reopen the tool or profile to confirm the setting persists and is not overridden by another proxy layer.
- Run a small real workload and observe login state, latency, success rate, and traffic consumption.
- Increase concurrency or workload size gradually while keeping diagnostic logs.
