Is SOCKS5 always faster than HTTP proxy?

No. SOCKS5 has a slightly smaller handshake overhead (one round-trip versus HTTP CONNECT for HTTPS, which is also one round-trip but with more bytes), but on warm connections the difference is under 5ms. SOCKS5 wins on UDP support, not on raw speed for HTTP(S) traffic.

Can SOCKS5 see my HTTPS traffic?

No. SOCKS5 operates at the transport layer (TCP/UDP), below TLS. It forwards encrypted bytes without decrypting them. Same is true for HTTP CONNECT proxies — both are blind to TLS payloads.

Why do antidetect browsers prefer SOCKS5?

SOCKS5 supports DNS-over-proxy (resolving target hostnames on the proxy side, not locally), which avoids DNS leaks that would expose the real ISP. It also handles UDP traffic cleanly, which matters for WebRTC isolation.

Does HTTP proxy work for non-web protocols?

No. Pure HTTP proxies only forward HTTP(S). SOCKS5 forwards any TCP (and UDP) protocol — useful for SSH tunneling, FTP, custom protocols, gaming clients, scrapers that use websockets, and so on.

Should I use SOCKS5 for web scraping?

For most scraping workloads against modern websites, either works. We default to SOCKS5 for residential IPs because it integrates better with anti-detect tooling and avoids DNS leak issues that show up at scale. For datacenter scraping where speed matters more than fingerprint cleanliness, HTTP CONNECT is fine.

Rotating vs Sticky Residential Proxies: When Each One Wins

Mark Lev

Network operations lead. Has been running residential SOCKS5 proxy stacks since 2019.

Two answers to opposite questions

Rotation and stickiness get sold as features of the same product, but they answer opposite questions. Rotation answers "how do I look like many people?" — every request (or every few minutes) exits from a different household IP, defeating rate limits and per-IP quotas. Stickiness answers "how do I keep looking like the same person?" — one IP holds for the length of a login, a cart, a conversation. Choosing wrong doesn't degrade performance; it inverts it.

Where rotation wins

High-volume scraping of search results, product listings, public records — thousands of stateless requests where each one benefits from a fresh identity.
Rate-limit evasion on APIs that quota per IP but don't bind sessions.
Geo-sampling — pulling the same page from fifty cities to compare pricing or ad delivery.

Failure mode to avoid: rotating through a flow that sets cookies. If request 1 gets a session cookie from IP A and request 2 presents it from IP B, sophisticated targets score the mismatch instantly.

Where stickiness wins

Anything with a login — social accounts, seller dashboards, webmail. The account's IP history is part of its trust score.
Multi-step funnels — cart → checkout → payment must ride one IP.
Antidetect browser profiles, where the whole point is a stable, coherent identity per profile.

Failure mode: treating sticky as permanent. Sticky windows on LunaProxy hold up to 30 minutes per session by design; for identities that must live for months, that's static ISP territory, not sticky residential.

Configuring both on Luna

Session control lives in the credential string — a session parameter pins an exit, its absence rotates. One balance drives both: point your scraper at the rotating endpoint and your antidetect profiles at session-pinned credentials, and each side gets the behavior it needs from the same 200M-IP pool. City and ISP filters apply identically in both modes.

The mixed pattern most teams end up with

Real operations are rarely pure. The common architecture: rotating residential for discovery and monitoring, sticky residential for every authenticated action, static ISP under the highest-value accounts. Budget flows the same direction — rotation is metered by volume, stickiness by identity count, which maps naturally onto per-GB and per-IP billing respectively.

FAQ

Can I change a sticky session's IP on demand?

Yes — issue a new session ID and you draw a fresh exit immediately. Sticky pins the IP for you, not against you.

Does rotation burn more IPs?

It uses more IPs but doesn't consume your pay-per-IP balance the way identity work does — rotating traffic on Luna is metered per-GB, so heavy crawls don't drain your per-IP pool.
