Use Browser DevTools when the problem lives inside a webpage or browser runtime. It is the best first tool for request initiators, CORS failures, cache behavior, cookies, payloads, response bodies, and page-load waterfalls. Use an HTTP debugging proxy such as mitmproxy, Charles, Fiddler Everywhere, Proxyman, or HTTP Toolkit when you must capture configurable traffic from a mobile app, desktop app, command-line client, container, or several clients. A debugging proxy is also the strongest choice when you need breakpoints, rewrites, mocks, or replay.
A proxy hostname is a domain name that resolves to the IP address of a proxy server. It consists of two parts, the domain name and the port. Some hostnames do not have ports as they are included by default based on the protocol being used.
Many of Twitch’s biggest personalities saw their viewcounts plummet last week as the streaming platform’s crackdown on viewbots seemingly took effect. Twitch had announced in late July that it would start cracking down on automated viewership.
HTTP 429 Too Many Requests means a server has rate-limited a client because it sent more requests than allowed within a specified period. First check the response for a Retry-After header and wait for the specified time before retrying. For APIs, scrapers, and automation, reduce your request rate or concurrency and use exponential backoff with jitter instead of immediately repeating failed requests.
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.
You can scrape Reddit with Python by requesting Reddit's structured data, handling cursor-based pagination, cleaning the returned JSON, and exporting posts or comments to formats such as JSON and CSV. Our open-source Reddit scraper uses a simple synchronous approach for smaller jobs and switches to asynchronous requests and proxy rotation for larger workloads.
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.
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.
Use `curl -i "https://example.com"` to show Hypertext Transfer Protocol (HTTP) response headers beside the response body. Use `curl -I "https://example.com"` only when a HEAD request matches your test. For GET headers without body output, run `curl -sS -D - -o /dev/null "https://example.com"`.
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?
