HTTP Proxy

An HTTP proxy is an intermediary server that forwards web (HTTP/HTTPS) requests on your behalf, able to read, cache and filter traffic at the application layer.

Last updated May 28, 2026

Definition

An HTTP proxy sits between a client and the web, forwarding HTTP and HTTPS requests on the client's behalf. Unlike SOCKS proxies, an HTTP proxy understands the web protocol, so it can inspect headers, cache responses, filter content and rewrite requests.

HTTP vs HTTPS proxying

For plain HTTP, the proxy sees the full request and can modify it. For HTTPS, the proxy typically uses the CONNECT method to open an encrypted tunnel it cannot read, preserving end-to-end TLS security.

When to choose an HTTP proxy

HTTP proxies are the natural fit for web scraping and browsing because they speak the same protocol as the target. For non-web traffic, a SOCKS5 proxy is more appropriate.

Examples

1

Setting HTTP_PROXY and HTTPS_PROXY environment variables for a scraper

2

Configuring an HTTP proxy in Chrome via the system network settings

Common Use Cases

Web scraping and crawling
Content filtering and caching
Monitoring or debugging web traffic
Geo-targeted browsing

Frequently Asked Questions

An HTTP proxy understands web traffic and can cache or filter it, while SOCKS5 is a lower-level tunnel that passes any TCP/UDP traffic without interpreting it.
No, not for properly secured HTTPS — the proxy tunnels the encrypted connection and cannot read its contents unless it performs TLS interception you trust.

All terms

SOCKS5

SOCKS5 is the latest version of the SOCKS proxy protocol. It routes any kind of network traffic — TCP and UDP — between a client and a server through a proxy, with optional authentication and no awareness of the underlying application.

Forward Proxy

A forward proxy sits between you and the internet and makes requests on your behalf. It is the everyday kind of proxy — used to change your IP address, filter traffic, or reach blocked content.

Read definition

SSL/TLS

SSL/TLS is the encryption protocol that secures data in transit on the web — the 'S' in HTTPS — protecting it from eavesdropping and tampering.

Read definition

Reverse Proxy

A reverse proxy sits in front of web servers and answers requests on their behalf, then quietly passes them to the right backend — handling load balancing, caching, HTTPS and security along the way.
