How to Make a HEAD Request with curl

`curl -I` sends a HEAD request. `curl -X HEAD` looks like it should do the same and does something subtly broken, which is a fine way to lose twenty minutes to a hanging terminal. The curl manual says so directly, and the reason is worth understanding because it applies to every method you might set by hand. This guide covers the correct syntax, the specification's rules about what servers may omit, and the cases where a HEAD tells you something a GET would not.

Proxy vs Firewall: What's the Difference?

A firewall decides whether traffic is permitted. A proxy makes requests on someone else's behalf. Those are different jobs, and most confusion between them comes from the fact that some products do both. They also sit at different layers, in different directions, for different reasons — and one of them is a security control while the other usually is not. This guide separates them properly, using the definitions from the standards rather than vendor marketing.

SNKRS Proxies: An Honest Look at What They Can and Cannot Do

Searching for SNKRS proxies usually means one thing, and that thing is prohibited by Nike's terms in language that leaves no room for interpretation. It also does not work the way people think it does, because SNKRS draws are randomised rather than first-come-first-served. This article covers what the terms say, how the release mechanics actually work, and the narrow set of jobs where proxies genuinely have a place.

Proxies and Virtual Credit Cards: What They Actually Protect

Virtual cards and proxies get recommended together as a privacy setup. They address different halves of the problem, and neither does what most people assume. A virtual card hides your card number from a merchant. It does not hide you. A proxy hides your address from a website. It does not hide your payment. Used together without understanding, they mostly make your legitimate transactions look suspicious.

How to Show Response Headers with curl

curl hides response headers by default. Four options reveal them, and they differ in ways that matter more than the documentation suggests. One of them sends a different request than the one you are trying to debug, which is a fine way to spend an hour chasing a discrepancy that does not exist. This guide covers all four, plus the JSON output most people do not know about and how the picture changes through a proxy.

XPath preceding-sibling: How It Works (With Examples)

`preceding-sibling` selects nodes that come before the context node at the same level of the tree. Simple enough — until you write `preceding-sibling::td[1]` and get a different cell than you expected. The reason is that `preceding-sibling` is a reverse axis, and position numbering on a reverse axis runs backwards. This guide covers what it selects, the numbering trap, how it differs from `preceding`, and the extraction patterns it exists to solve.

JSON vs CSV: Which Format Should You Use?

The usual comparison says JSON is structured and CSV is simple. That is true and it misses the difference that causes real problems. JSON is a specification with mandatory rules. CSV is a description of what most implementations happen to do, written down after the fact. That asymmetry explains nearly every CSV problem you have ever had, and it should shape which format you pick.

How to Build an Aggregator Website: A Practical Guide

An aggregator is a website whose value comes from other people's content, organised better than they organised it. Jobs, property, prices, news, events. The interesting problems are not technical. Getting data is the easy part; deduplicating it, keeping it fresh, and staying on the right side of the law are where projects die. This guide covers the whole shape of it — data sources in order of preference, the legal layer, the architecture, and the failure modes.

Unblocking GoGuardian: What Works, What Doesn't, and Why

GoGuardian blocks a site and the obvious question is how to get round it. The obvious answer — a proxy or VPN — does not work in the situation most people are in, and it is worth understanding why. The filtering does not happen on the network. It happens inside the browser on the device. This guide covers what GoGuardian actually is, the legitimate routes to getting something unblocked, and the difference between a school-managed device and your own.

What Is Proxy Pricing? A Guide to How Proxies Are Billed

Proxy providers bill in at least four different ways, and the headline numbers are not comparable across them. A gigabyte and an IP address are not the same unit of anything. Which means the cheapest-looking provider is frequently the expensive one for your particular workload, and working out which is which takes about ten minutes of arithmetic. This guide covers the models, the hidden costs, the arithmetic, and the pricing patterns that should make you cautious.

Best Twitter/X Proxies in 2026: An Honest Assessment

That reading changes the answer to "which proxies should I buy" for most people, and we would rather lead with it than bury it. What follows: the terms, the `robots.txt`, the narrow set of jobs where proxies remain sensible, and how to choose for those.

What Is a 415 Status Code? Causes and Fixes

A 415 means the server understood your request and refused the format you sent the body in. It is not about your data being wrong — it is about the wrapper. Which is why the fix is almost always a header rather than a payload change, and why people who go looking in their JSON find nothing. This guide covers what the specification actually says, the handful of causes that account for nearly every case, and how to tell 415 apart from the three status codes it gets confused with.

What Is a Proxy Port? A Practical Guide

A proxy port is the number after the colon in `proxy.example.com:8080`. It tells the server which service on that machine should handle your connection.

This guide covers what the number means, why the familiar ones became familiar, what the official registry actually records about them — which is not what most people assume — and how to tell a port problem from everything else.

Best YouTube Proxies in 2026

YouTube serves a different page to almost every visitor — different trending shelf, different ads, different availability. That variability is why teams doing ad verification, market research, localization QA, and public metadata collection reach for proxies. This guide covers which proxy type actually works on YouTube, what to check before you buy, what the work costs at three volume tiers, and how to set it up without tripping over the usual errors. Entry rates across the residential market span $0.79 to $7.00 per GB for the same category of product. Here is what that difference buys, and when it buys you nothing at all.

Best Bing Rank Tracking Tools

Microsoft retired the Bing Search APIs on 11 August 2025, which quietly removed the official route to Bing results and left every rank tracker relying on scraping. Meanwhile the free Bing Webmaster Tools API still reports your real average position from actual impressions — more accurate than any scraper, and almost nobody uses it. This guide covers what changed, what the free option gives you, what the paid tools cost for Bing specifically, and the honest case for not tracking Bing at all.

Best Rank Tracking APIs

A rank tracking API gives you search engine results as structured data, on demand, without you having to fight bot detection yourself. The catch is that the same workload can cost $27 a month or $725 a month depending purely on which provider you pick — and the headline prices do not make that obvious. This guide covers the two very different products both sold as "rank tracking APIs", verified per-1,000 pricing from official pages, a worked cost model for a realistic keyword set, and the case where you should not buy one at all.

Best Residential Proxy Providers in 2026

Residential proxy pricing runs from under a dollar to seven dollars a gigabyte for what is described as the same product, which tells you the headline rate is not measuring what you think.

LunaProxy Is Gone: What Happened and What to Use

If you came here to compare LunaProxy's pricing, the comparison is moot: **the service stopped operating on 28 January 2026** and its domain no longer resolves.

LunaProxy was one of more than ten brands fronting the same network. This covers what happened, what it means if you had a balance with them, and the vetting that would have flagged the risk beforehand — questions worth putting to any proxy provider, us included.

How to Test Your Proxies

Most proxy testing stops at "does it connect", which tells you almost nothing. A proxy can connect perfectly and still be useless for your job. The four things worth measuring are connectivity, geolocation accuracy, leaks, and success rate on your actual target — and the last one matters more than the other three combined. This guide gives you runnable commands for each, a script that tests a whole list concurrently, and the reason free proxy checker sites cannot answer the question you care about.

Axios vs Fetch

One difference matters more than all the others combined: fetch does not reject on HTTP errors. A 404 or a 500 resolves successfully and your code carries on. Everything else — bundle size, syntax, interceptors — is preference. That one is a bug generator, and it is documented behaviour rather than a quirk. This guide covers what each tool actually does per its own documentation, the boilerplate you write to make fetch behave, and the proxy gap in Node that catches people out.

Best Proxy Browser Extensions in 2026

The proxy extension recommended in almost every list on this subject is no longer maintained and was disabled in Chrome over the Manifest V3 migration.

curl vs wget

The shortest honest answer: curl behaves like cat and wget behaves like cp. One writes to your screen, the other writes a file.

Ignore SSL Certificate Errors with curl

The answer is curl -k, and it takes one second. The reason you should read further is that -k does not fix anything — it switches off the check that noticed the problem. Most certificate errors have a specific, identifiable cause, and most of them have a fix that takes about the same effort as typing -k while leaving verification intact.

Antidetect Browsers: Is It Worth It in 2026?

Antidetect browsers run many isolated browser profiles on one machine, each presenting a different device, so accounts do not appear to share hardware.
