Configuring a proxy in A-Parser

### How to make A-Parser work with a proxy: a step-by-step guide to keep the parser running and your IP from getting banned

A-Parser is the Swiss Army knife of the parsing world. It is powerful, flexible, and multi-threaded. But there is a caveat: any industrial-scale work runs into limits and blocks from target sites. Google, Yandex, and other platforms quickly detect and ban IP addresses that send too many requests.

To keep your parser running smoothly and your tasks completed without headaches, you need to properly “befriend” it with a proxy. This is not just a recommendation, but a prerequisite for stable operation.

#### Why does a parser need a proxy?

If you parse more than 10 requests per day, the answer is obvious — **to avoid being banned**. But if you dig deeper, high-quality proxies solve several key tasks at once:

* **Scaling:** A-Parser can work in hundreds of threads. But without proxies, all these threads will come from a single IP address, which will be blocked in a minute. With a proxy pool, each thread gets its own unique address.
* **Bypassing protection and CAPTCHA:** The main reason for bans is exceeding the limits on requests from a single IP address. Proxy rotation allows you to bypass these restrictions and encounter CAPTCHAs much less often.
  * **Geo-targeting:** Need to collect search results as seen by a user in Berlin or New York? Just load the proxy of the desired country into the parser, and it will receive relevant, geo-dependent data.
  * **Anonymity:** You protect your main IP address from being added to spam lists and blacklists.

**Which proxy to choose?** **Rotating residential** or **mobile proxies** are best suited for parsing. They provide maximum trust, as their IP addresses belong to real home and mobile providers.

### Step-by-step proxy setup in A-Parser

The process consists of several steps: create a preset, prepare a proxy file, run a check, and make sure everything works.

### Step 1: Collect proxy credentials

The first and most important step is to make sure you have a complete set of credentials for authorization. These “keys” will allow your application or browser to connect to the proxy server and route traffic through it.

Be sure to prepare the following data:

* **IP address** (host server)
* **Port** for connection
* **Login** and **password** for authorization
* **Protocol type** (HTTP/HTTPS or SOCKS5)

#### Step 2: Create a preset for our proxies

To avoid entering the same parameters every time, let's create a separate preset (settings template) for them.

1. In the left menu of A-Parser, go to the **“Proxy Checker”** section.

*Fig. 2. Screenshot of the main interface of A-Parser Pro, showing the location of the menu. To get started, go to the “Proxy Checker” section.*

1. Click the **“Add Proxy Checker”** button.

*Fig. 3. Screenshot of the “Proxy Checker” section in A-Parser, showing the “Add Proxy Checker” button for creating a new proxy checker.*

1. Click the **“Add new...”** button (Add new preset).

*Fig. 4. Screenshot of the “Settings” section in A-Parser, showing the transition to the “Proxy Checker Settings” tab and the “Add New Preset” button for creating a new preset.*

1. In the window that appears, enter a meaningful name, for example, **CyberYozh**, and click **“OK”**.

*Fig. 5. Screenshot of the dialog box in A-Parser showing the process of creating a new preset. Enter the name of the preset in the field, in this case, “CyberYozh.”*

Now all further settings will be linked to this preset.

#### Step 3: Configure authorization

This is the most important step. Tell the parser how to work with your proxies that have a login and password.

1. Make sure that your preset (“CyberYozh”) is selected in the **“Settings”** drop-down list.

*Fig. 6. Screenshot of the settings for the preset created in A-Parser, in this case — “CyberYozh”.*

1. Scroll down the page and check the **“Use proxy authorization”** box.

*Fig. 7. Screenshot of the proxy checker settings in A-Parser, showing the activation of the “Use proxy authorization” option.*

1. Leave the **“Login for authorization”** and **“Password for authorization”** fields blank. A-Parser is a smart tool, and it will extract the authorization data from your proxy list itself, provided it is in the correct format.

*Fig. 8. Screenshot of the proxy checker settings in A-Parser, showing the activation of the “Use proxy authorization” option. The login and password fields remain empty, as the data will be read from the file.

1. After that, be sure to click the **“Save”** button to apply the changes to the preset.

#### Step 4: Prepare and upload the proxy list

A-Parser automatically creates a folder for each new preset. This is where we will put our proxy list.

1. Open the folder where A-Parser is installed. Go to: `.../aparser/files/proxy/`.
  2. Inside, you will see a folder with the name of your preset — **CyberYozh**. Open it.

*Fig. 10. Screenshot of the file manager showing the A-Parser folder structure. A folder with the same name was automatically created for the “CyberYozh” preset, in which you need to place the proxy.txt file.*

1. Create or open (if it already exists) a text file named `proxy.txt` in this folder.
2. Open this file and paste your proxy list into it. **The format must be strictly** `login:password@IP_address:port`. Each proxy should be on a new line. Don't forget to save the file after making changes.

*Fig. 11. Screenshot of the proxy.txt text file showing the correct format for entering data for proxies with authorization: login:password@IP_address:port.*

#### Step 5: Run the check

All settings are ready, the file is in place. It's time to check if our proxies will “come to life” in the parser.

1. Return to A-Parser and go to the **“Proxy Checker”** section in the left menu.
2. The parser will automatically pick up the `proxy.txt` file from the desired folder.
3. **Done**.

![](/media/mdeditor/image13_20250901043120950267.png)
*Fig. 12. Screenshot of the “Proxy Checker” section in A-Parser, showing the addition of a new proxy checker using the created preset.*

The proxy checker will start working. At first, you will see that it is running, but there are no live proxies yet.

#### Step 6: Check the result

Once the check is complete, refresh the page. You should see that the “Total Live” counter shows the number of successfully checked proxies. If the number matches the number of proxies in your file, congratulations, everything is set up perfectly!

*Fig. 13. Screenshot of the “Proxy Checker” section in A-Parser, showing the result of a successful check. The “Total Alive” counter shows the number of working proxies ready for use.*

Now A-Parser is ready to use this pool of “live” proxies to perform your tasks.

### Conclusion

You're awesome! The setup is complete. Remember: the basis for successful and smooth parsing is not only powerful software, but also high-quality, reliable proxies. Saving money on them almost always leads to wasted time, frustration, and banned IPs.
