Configuring a proxy in A-Parser

How to Connect A-Parser with Proxies: A Step-by-Step Guide for Stable Data Scraping

A-Parser is the Swiss Army knife of data collection automation. Powerful, flexible, and multi-threaded. But there’s a catch: any industrial-scale operation eventually hits the limits set by target websites. Search engines and large platforms impose restrictions on the number of requests from a single IP address to balance the load.

To keep your tool running smoothly and ensure tasks are completed without headaches, you need to properly "connect" it with proxies. This isn't just a recommendation; it's a mandatory requirement for stable performance.

Why Does a Data Collection Tool Need Proxies?

If you make more than 10 requests a day, the answer is obvious — to ensure connection stability and stay within limits. But if you dig deeper, high-quality proxies solve several key challenges:

• Scalability: A-Parser can operate in hundreds of threads. Without proxies, all these threads will use a single IP, which will quickly exhaust its limits. With a proxy pool, each thread gets its own unique address.
• Request Limit Management: Proxy rotation helps distribute requests evenly, ensuring smooth data collection and reducing the risk of interruptions due to rate limiting.
• Geo-targeting: Need to scrape search results as seen by a user in Berlin or New York? Just load proxies from the required country, and the program will receive relevant, geo-dependent data.
• Confidentiality: You maintain the privacy of your main IP address and keep your connection reputation high.

Which proxy should you choose? For data collection, rotating residential or mobile proxies are the best fit. They provide a high level of trust because their IP addresses belong to real home and mobile providers.

Step-by-Step Proxy Setup in A-Parser

The process consists of several stages: creating a settings preset, preparing the proxy file, running a check, and ensuring everything works.

Step 1: Gathering Proxy Credentials

The first and most important step is to ensure you have a full set of authorization data. These "keys" will allow your application or browser to connect to the proxy server and route traffic through it.

Make 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: Creating a Preset for Our Proxies

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

1. In the A-Parser left menu, go to the "Proxy Checker" section.

1. Click the "Add Proxy Checker" button.

1. Click the "Add ne..." button (Add new preset).

1. In the pop-up window, enter a clear name, for example, CyberYozh, and click "OK".

Now all further settings will be tied to this preset.

Step 3: Configuring Authorization

The most crucial step. We specify how the program should handle proxies that require a login and password.

1. Ensure that your preset ("CyberYozh") is selected in the "Settings" dropdown list.

1. Scroll down the page and check the "Use proxy authentication" box.

1. Leave the "Login for authentication" and "Password for authentication" fields empty. A-Parser is a smart tool; it will automatically extract the credentials from your proxy list if they are in the correct format.

1. After this, be sure to click the "Save" button to apply the changes to the preset.

Step 4: Preparing and Uploading the Proxy List

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

1. Open the folder where A-Parser is installed. Navigate to: .../aparser/files/proxy/.
2. Inside, you will see a folder named after your preset — CyberYozh. Open it.

Fig. 10. Screenshot of the file manager showing the A-Parser folder structure. A folder named "CyberYozh" was automatically created for the preset, where the proxy.txt file should be placed.

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. The format must strictly be login:password@IP-address:port. Each proxy on a new line. Don't forget to save the file.

Step 5: Running the Check

All settings are ready, and the file is in place. It's time to see if our proxies "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 corresponding folder.
3. Done.

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. Initially, you will see it running, but there won't be any "alive" proxies yet.

Step 6: Checking the Results

Once the check is complete, refresh the page. You should see the "Total Alive" counter showing the number of successfully verified proxies. If the number matches the amount of proxies in your file — congratulations, everything is set up perfectly!

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

A-Parser is now ready to use this pool of "alive" proxies for your tasks.

Conclusion

Great! The setup is complete. Remember: the foundation of successful and uninterrupted data collection is not just powerful software, but also high-quality, reliable proxies. Saving on them almost always leads to connection issues and task interruptions.
