Goproxy
An HTTP proxy library for Go
Features
- HTTP Proxies - Provides a library for building custom HTTP and HTTPS proxy servers in Go with full request/response control.
- MITM Proxies - Provides a man-in-the-middle proxy library that caches generated TLS certificates for efficient HTTPS inspection.
- Session and Traffic Routing - Filters proxy traffic by destination host or URL path and routes matched requests to custom handlers.
- Destination Host Filters - Ships host-based traffic filtering using exact match and regex patterns for selective proxy application.
- HTTP Interceptors - Provides HTTP request and response interception with full inspection and modification capabilities.
- HTTPS Decryption Proxies - Implements HTTPS interception via dynamic TLS certificate generation for encrypted traffic inspection.
- Custom Proxy Frameworks - Routes HTTP requests matching a relative path to a custom handler instead of forwarding to the original destination.
- HTTP Request and Response Modifiers - Intercepts both HTTP and decrypted HTTPS traffic at request and response stages for inspection and modification.
- On-The-Fly Certificate Generators - Generates per-host TLS certificates on the fly during the TLS handshake for HTTPS interception.
- Transparent HTTPS Inspections - Decrypts HTTPS traffic using dynamically generated TLS certificates for full traffic visibility.
- Custom CA Injections - Allows users to replace the default proxy CA with a custom one for client trust.
- Proxy CA Replacements - Replaces the default proxy CA certificate with a user-provided one for client trust.
- MITM Certificate Caches - Caches generated MITM certificates for reuse across requests to the same host to reduce CPU overhead.
- Certificate Caches - Caches generated MITM certificates in memory to reduce CPU overhead across requests.
- Host-Based Matchers - Applies proxy rules selectively by matching request destination hosts against exact names or regex patterns.
- Proxy Lifecycle Error Handling - Captures and responds to connection errors in a proxy server with custom error messages over the raw connection.
- Path-Based Handler Routings - Routes HTTP requests matching a relative path to a custom handler instead of forwarding.
- Traffic Filtering Proxies - Filters traffic by destination host using exact match or regular expression patterns.
- Raw Connection Error Writers - Catches transmission errors and writes custom error responses directly over the raw TCP connection.
- Custom Handler Injection - Redirects HTTP requests matching a relative path to a custom handler instead of forwarding to the original destination.
- Networking And Proxies - HTTP proxy library.
