A-B
Anonymous Proxy
A proxy that hides your real IP from the target website. The site knows a proxy is being used but cannot identify you.
Backconnect Proxy
A gateway that automatically assigns different IPs from a pool. You connect to one address; rotation happens behind the scenes. This is the standard architecture for rotating proxies at Botosaur.
Bandwidth
Data transferred through the proxy, measured in GB. Residential providers often charge per GB; ISP providers usually offer unlimited bandwidth per IP.
C-D
CAPTCHA
A challenge test to distinguish humans from bots. Often triggered by suspicious proxy traffic patterns.
Datacenter Proxy
A proxy hosted in a commercial data center. Fast and cheap, but easier for websites to identify and block.
DNS Leak
When DNS queries bypass the proxy and go to your ISP, exposing visited domains. See our security guide for testing.
F-G
Fingerprinting
Identifying visitors by browser attributes — screen resolution, fonts, WebGL data, timezone, etc. Even with a proxy, a unique fingerprint can identify you.
Forward Proxy
The standard model: proxy sits between client and internet, masking client identity. This is what most people mean by "proxy."
Gateway
The entry point your client connects to. A backconnect gateway routes your connection through one of many exit IPs.
H-I
HTTP Proxy
Operates at the HTTP protocol level. Can read/modify headers and cache content. Handles HTTPS via CONNECT tunnel. See HTTP vs SOCKS5 comparison.
IP Rotation
Automatically cycling through different IPs across requests or sessions. Reduces risk of any single IP being blocked.
ISP Proxy
Uses IPs registered to consumer ISPs but hosted on datacenter infrastructure. Combines residential trust with server speed. Also called "static residential" proxies.
L-P
Latency
Time delay between sending a request and receiving the response, measured in milliseconds. Datacenter proxies have the lowest latency.
Proxy Pool
The collection of IPs available to a proxy service. Larger pools mean less chance of reusing flagged addresses. Botosaur maintains pools across multiple geographies.
Rate Limiting
Website-imposed caps on requests per IP within a time window. IP rotation is the primary countermeasure.
R
Residential Proxy
Uses IPs assigned by consumer ISPs to real households. Highest trust scores — indistinguishable from normal home traffic.
Reverse Proxy
Sits in front of servers, handling incoming client requests. Used for load balancing, SSL termination, and DDoS protection. Cloudflare and Nginx are common examples.
S
Session
A persistent connection using the same proxy IP. Controlled via session ID parameters with rotating proxies.
SOCKS5
Protocol supporting any TCP or UDP traffic. Doesn't inspect data — just relays packets. Supports native authentication. See protocol comparison.
Static Proxy
A fixed IP that doesn't change. Best for account management and consistent identity tasks.
Subnet
A range of IPs sharing a common network prefix. Websites can block entire subnets at once. Diverse subnet distribution reduces this risk.
T-W
Transparent Proxy
Forwards your real IP to the target server. Offers no anonymity. Used by organizations for content filtering.
Upstream Proxy
A second proxy in a chain, adding another layer of anonymity or geographic routing.
Whitelisting
Authentication by registering your source IP. No credentials needed — the proxy allows connections from whitelisted IPs. See authentication guide.
