For authorized Amazon data collection, rotating residential proxies are usually the best starting point. Use sticky sessions when a worker must preserve a marketplace, delivery destination, cookies, variant, or seller-offer flow.
It seems inevitable today that everyone’s had at least one interaction with a price comparison site. From cars and apartments to hotels and flights, there’s a price comparison site, also called a comparison shopping engine (CSE), dedicated to finding you the best price.
I want to scrape Reddit data. Simple enough, right? It turns out that most Reddit scraping tutorials fall into two categories: the “here’s how to grab 10 posts” quick and messy scripts, or the over-engineered enterprise solutions that feel like using a spaceship.
As builders or developers we do data transfers from the command line and when it comes down to it, two tools dominate the conversation. cURL and Wget are both great tools and widely used, but people often mix them together. However, each one of them serves different purposes and works best in different scenarios.
To use cURL with a proxy, add --proxy protocol://host:port to the command. If the proxy requires a username and password, add --proxy-user 'username:password'. For a SOCKS5 proxy that should resolve the destination hostname, use the socks5h:// scheme.
cURL, short for Client URL, is a command-line tool used to send and receive data from servers using a wide variety of protocols. It’s built on a library called libcurl and supports protocols like HTTP, HTTPS, FTP, SMTP, LDAP, and more.
Testing UDP can be tricky and confusing: few apps support it, SOCKS5 requires a separate UDP ASSOCIATE handshake to relay datagrams, and browsers neither expose raw UDP sockets nor forward UDP‐based transports like QUIC (HTTP/3) through proxies.
As a developer when working with APIs, troubleshooting HTTP responses, or optimizing server performance, response headers can tell you a lot from content type and caching rules to redirect info and rate limits. While browsers hide most of this behind DevTools, cURL gives you full, direct access from the command line.
What do you do when you need every packet that leaves your iPhone or iPad to pass through a proxy, yet the network you are on blocks or throttles traditional VPN tunnels?
If you ever worked with APIs or tested HTTPS endpoints using curl, you’ve probably run into a frustrating SSL error — especially when dealing with self-signed certificates or local environments. To quickly get past it, many developers use the -k or —insecure flag to “ignore SSL”. But what exactly does this do? And is it safe?
Error code 502 (or 502 Bad Gateway) is one of the most common codes you can come across, second only to the infamous error code 404. This is because the error code happens on almost every website, from Gmail to Twitter (X), and even Cloudflare.
