What Is an HTTP Proxy and How Does It Work?
An HTTP proxy sits between a client and a destination server. It receives web requests from the client, forwards them to the destination, and returns the response. The name can be confusing. An HTTP proxy is not limited to websites that use plain HTTP. It can also carry HTTPS traffic by using the CONNECT method to open a tunnel to the destination server. Direct Answer An HTTP proxy is a server that accepts HTTP-style proxy requests and forwards them through another network route. It can inspect unencrypted HTTP requests. For HTTPS destinations, it commonly creates a CONNECT tunnel that carries...
User Agent vs Proxy: What’s the Difference?
A user agent is the browser, application, or software client that sends a web request. A proxy is an intermediary that forwards that request through another network route. In simple terms, the user agent describes the client, while the proxy affects where the connection comes from. Understanding that difference matters when testing websites, configuring Playwright or Puppeteer, or troubleshooting a browser that still receives unexpected results after the proxy has changed. Direct Answer A user agent operates at the client and browser level. A proxy operates at the network level. Changing one does not recreate the other, so reliable testing...
What Is Headless Browsing?
Headless browsing means running a real browser engine without opening a visible browser window. The browser can still load pages, execute JavaScript, store cookies, click elements, wait for network responses, and render the DOM. The difference is that the browser is controlled through code and runs in the background. For web scraping, testing, scheduled page checks, and browser automation, headless browsing is useful when a simple HTTP request cannot access the same page state that appears after browser rendering or interaction. It is not always the best choice. If the required data is already available in raw HTML or a...
Is Web Scraping Legal? Practical Checks for Teams
Web scraping can be legally acceptable in some situations and risky or prohibited in others. The answer depends on the source, the type of data, how access happens, the website’s terms, privacy rules, contract obligations, jurisdiction, and what the collected data will be used for. The safest way to assess a project is not to ask whether “web scraping” is legal in the abstract. A more useful question is whether a specific team can collect specific data from a specific source, for a specific purpose, using a specific access method. This article provides a practical risk-review framework for business and...
What Is Web Scraping?
A product page may show a title, price, rating, seller, and availability to a human reader. Web scraping turns those visible fields into structured records that software can compare, validate, search, and store. The output may be saved as CSV, JSON, a database table, or an internal dashboard. This makes it possible to analyze information across many public pages without manually copying every value. Real-world web scraping involves more than downloading HTML. A dependable workflow must identify the right fields, handle missing or JavaScript-rendered content, validate the extracted values, and respect the technical, privacy, and policy limits surrounding the source....
What Is a Datacenter Proxy?
A datacenter proxy routes your internet traffic through an IP address provided by a hosting company, cloud provider, or data center network. The destination website sees the proxy IP instead of your original public IP address. Datacenter proxies are widely used because they are fast, relatively affordable, and easy to scale. They work well for website testing, fixed-IP access, public web data tasks, API requests, and other workflows that do not require a consumer broadband connection. The main tradeoff is that websites and IP databases can often identify the IP as belonging to hosting or server infrastructure. That does not...
Residential Proxy vs Datacenter Proxy: Which Should You Use?
Residential proxies and datacenter proxies can both change the IP address a website sees. But they are not built for the same job. A residential proxy uses an IP address associated with a residential or ISP-style network. A datacenter proxy uses an IP address from hosting, cloud, or data center infrastructure. That difference affects speed, cost, reliability, IP classification, and where each proxy type makes sense. If you are checking localized pages, managing browser profiles, or working with account-based sessions, the network source may matter. If you are running backend tests, response checks, API routing, or internal QA tasks, paying...
Static vs Rotating Residential Proxies: Which Should You Use?
Choosing a residential proxy is not just about picking a country, checking the price, or choosing the largest IP pool. The more practical question is this: should the IP stay the same, or should it change during the workflow? That decision matters more than many users expect. A dashboard login, seller account, social media profile, or long-running browser session usually works better with a stable IP. A regional search check, ad review, product availability check, or larger data access task may need many residential IPs across sessions instead of one fixed route. A static residential proxy keeps the same residential...
What Is a Residential Proxy? A Practical Guide
Not every proxy IP is treated the same way. One IP may come from a cloud hosting provider. Another may look like it belongs to a normal home internet connection. For websites, apps, risk systems, ad platforms, and regional content services, that difference can matter. A residential proxy is a proxy that routes traffic through an IP address associated with a residential internet connection. Instead of seeing your original public IP address or a typical data center IP, the destination website sees the residential proxy IP. This guide explains what a residential proxy is, how it works, what a residential...
What Is a Proxy Server? Meaning, Types, and How It Works
A proxy server is a middle server that forwards requests between your device and the website, app, or online service you want to reach. Instead of connecting directly to the destination, your browser, application, or script sends traffic to the proxy server first. The proxy server then sends the request onward and returns the response to you. That middle position is what makes proxy servers useful. A proxy can change the visible IP address a website sees, route traffic through a selected server, separate traffic for different tools, or help keep a browser or application workflow more consistent. This guide...
What Is an IP Quality Score?
You check an IP address, and the result looks confusing. The IP works. The location looks right. Your proxy checker shows a new visible IP. But another tool gives the same IP a low quality score, a risky label, or a warning about proxy, VPN, abuse history, hosting infrastructure, or blacklist status. That does not automatically mean the IP is unusable. An IP quality score is not a universal pass-or-fail grade. It is a risk estimate created by a specific tool based on signals such as IP type, ASN, ISP, hosting labels, proxy or VPN detection, abuse reports, blacklist data,...
Why Is My IP Location Wrong? Common Reasons and Fixes
You check your IP location and expect to see your real city, your selected proxy region, or at least the right country. Instead, the lookup result shows a nearby city, another state, a datacenter location, or an ISP name that does not match what you expected. This is more common than most people think. In many cases, it does not mean your device is broken, your connection is unsafe, or your proxy is unusable. IP location is based on databases, network records, routing information, and ISP data. It is not GPS, and it is not designed to pinpoint your exact...
