Proxy & Web Scraping Glossary
Every term explained in plain English. No jargon left behind
A
Anonymous Proxy
An anonymous proxy forwards your internet requests and swaps your IP with its own. It masks IP and keeps things anonymous.
Anti Detect
An anti detect isn't just a fancy tool. It's what you use to mask, spoof, or randomize the digital fingerprint of your device.
ASN
An ASN's a unique number given to a bunch of IP address ranges that one organization controls.
B
Backconnect Proxy
A backconnect proxy is a gateway server routing each outbound request through a different IP address from a rotating pool of residential or datacenter nodes.
Bandwidth
Bandwidth is all about max data transfer across a network connection, measured in bps or bytes per second.
Browser Fingerprint
A browser fingerprint sticks out like a sore thumb. It's built from browser details: user agent, screen resolution, fonts, timezone, WebGL data.
C
Captcha
A captcha throws a wrench in web scraping by challenging users to prove they're not bots.
Concurrency
Concurrency lets a proxy network or system juggle multiple requests, sessions, or tasks at the same time, without them getting in each other's way, using...
Connection Timeout
A connection timeout's what you see when a client can't hook up with the server before the clock's up, causing a request timeout error with no data exchanged.
Cookies
A cookie's just a small piece of data stored in your browser by a web server.
CSV
A CSV is a plain-text file format. It stores tabular data as comma-separated values. Each line is a row; each field split by a comma is a column.
D
Data Extraction
Data extraction automates the grind of grabbing and organizing data from web sources at scale.
Data Normalization
Data normalization adjusts raw values into a uniform range or structure, making it possible to compare, merge, or analyze different datasets accurately.
Data Parsing
Data parsing automates the extraction, interpretation, and conversion of raw data from web sources into structured formats for analysis or storage at scale.
Datacenter Proxy
A datacenter proxy's just a middleman server you rent from a cloud or hosting company. It passes your internet traffic through an IP not from your usual ISP.
Distorting Proxy
A distorting proxy forwards a client's request but deliberately tosses in a fake IP address in the HTTP headers.
DNS
DNS is a naming system. It takes user-friendly domain names and spits out machine-readable IP addresses. DNS resolution is how it handles that translation.
E
Elite Proxy
An elite proxy hides the original IP completely, forwarding web requests without any hint of that IP or a proxy being in use, so traffic looks like it's...
Error 403
Error 403. That's what you get when a web server says, 'I see your request, but you're not getting in.' It's not like a 404 where the thing's missing.
Error 407
An error 407 pops up when a client tries to use a proxy server without the right proxy credentials. It's your proxy saying 'nope,' not the destination server.
Error 429
An error 429 pops up when you've hit the request limit set by a server for a specific endpoint within a time window.
ETL Pipeline
An ETL pipeline runs a sequence that'll take raw data from one or multiple sources, shape it into a structured format, and dump it into places like a data...
H
High Anonymity Proxy
A high anonymity proxy completely hides your original IP and doesn't send any identifying headers, like X-Forwarded-For or Via, to the server.
HTTP Proxy
An HTTP proxy shuffles HTTP requests and responses between a client and a destination web server, hiding the client's original IP address.
HTTPS Proxy
An HTTPS proxy sits between you and the destination, passing encrypted HTTPS traffic along the way.
I
IP Address
An IP address is a number routers use to send traffic to your device. Every device gets one.
IP Ban
An IP ban's a server-side wall that stops one or more specific IP addresses from accessing a website or service.
IP Rotation
IP rotation automates the cycle of different IP addresses for each request or session. You're not sticking with one IP tied to your traffic.
IPv4
IPv4 uses a 32-bit IP addressing scheme that identifies devices on a network by a four-part numeric format like 192.168.1.1.
IPv6
IPv6 steps in where IPv4 left off.
ISP Proxy
An ISP proxy uses IP addresses that ISPs assign to end users.
P
Port Numbers
Port numbers are just 16-bit numbers given to processes or services on a host. TCP/UDP ports send network traffic to the right app over socket connections.
Proxy Authentication
Proxy authentication checks if a client's legit before any requests move past a proxy. It's like a gatekeeper for forwarding traffic.
Proxy Pool
A proxy pool is just a bunch of proxy servers acting like one big virtual proxy.
Proxy Rotation
Proxy rotation automatically cycles through multiple IPs. Each outbound request or sequence gets a new IP.
Proxy Server
A proxy server sits between your device and the internet, shuffling internet requests through a different IP address.
R
Rate Limiting
Rate limiting stops clients from sending too many requests to a server in any given timeframe.
Residential Proxy
A residential proxy's basically a real IP slapped on by an ISP to a physical device.
REST API
A REST API's a set way for software to talk over HTTP, using methods and endpoints. It gives web services a known way to share resources.
Reverse Proxy
A reverse proxy sits between clients and one or more web servers, intercepting their requests and handing them off to the right backend.
Rotating Proxy
A rotating proxy assigns a new IP from a shared pool each time you make a request or after some time. No single IP gets flagged by target sites.
S
Shared Proxy
A shared proxy is a proxy server where multiple users access the same IP and bandwidth simultaneously.
socks4
A socks4 is a TCP/IP proxy protocol. It routes network traffic through an intermediary proxy.
SOCKS5
A SOCKS5 is a proxy server configuration that routes internet traffic through an intermediary server at the transport layer.
SSL Proxy
An SSL proxy sits between a client and a destination, setting up an encrypted link using Secure Socket Layer or TLS.
Static Proxy
A static proxy sticks a single, consistent IP on all outbound requests during a session or account, unlike rotating proxies that flip addresses for every...
Sticky Session
Sticky sessions pin your requests to the same server or proxy IP during a session window.
Structured Data
Structured data standardizes how you organize and label web content, like JSON-LD implementation or schema markup.
Subnet
A subnet's a carved-out piece of a larger IP network. CIDR notation and a subnet mask define it, grouping IP addresses under a common routing domain.
T
TCP Proxy
A TCP proxy; it's in layer 4 of the OSI model and works right at the transport layer. It just forwards raw TCP connections between a client and a server.
Threads
Threads is a decentralized, text-based social network, rolled out by Meta as a Twitter/X rival linked to Instagram.
TLS Fingerprint
A TLS fingerprint's a unique ID from the parameters swapped during an SSL/TLS handshake—cipher suites, TLS versions, extension order.
Tor vs Proxy
Tor vs proxy isn't just different tools for IP masking; they're distinct in how they achieve it.
Transparent Proxy
A transparent proxy sits at the network level, catching and shoving client traffic onward without the client lifting a finger.
U
UDP Proxy
A UDP proxy's a stateless proxy server moving User Datagram Protocol packets between a client and a destination without a persistent connection.
Unstructured Data
Unstructured data? It's just a jumble without predefined schema or format.
Uptime
Uptime? It's just the percentage showing how often a proxy network or server works without hiccups. That's your reliability mark in a service level agreement.
User Agent
A user agent is a string in HTTP request headers. It tells the server what software, browser, OS, and device are making the request.
W
Web Crawler
A web crawler's just an automated bot that roams around the internet, hopping from link to link to grab data for indexing, scraping, and big extraction jobs.
Web Scraping
Web scraping means automating how you grab structured data from websites.
Web Unblocker
A web unblocker?
Whitelisting
Whitelisting lets you permit access only to pre-approved IP addresses, users, or sources via access control lists. It's the opposite of blocklisting.
