+ HTTP server +

+

+ Caddy's HTTP server is one-of-a-kind: powerful, extensible, efficient, and modern. +

+
+
+

HTTP versions

+
+ Caddy's HTTP server supports all major versions of HTTP and enables them by default. You can customize exacttly which versions you want to serve. +
+
    +
  • HTTP/1.1
    • +
  • HTTP/2
    • +
  • HTTP/2 over cleartext (H2C)
    • +
  • HTTP/3
    • +
+
+
+

Listen interfaces

+
+ Each HTTP server can listen on one or more sockets and network interfaces. For ports, you can specify specific host interface or all interfaces with just a port. All varieties of unix sockets are also supported. +
+
    +
  • TCP
    • +
  • UDP
    • +
  • Unix sockets
    • +
+
+
+

Listener wrappers

+
+ Listeners can be wrapped by modules that operate at the connection-accept level. +
+
    +
  • Redirect HTTP on HTTPS port
    • +
  • PROXY protocol
    • +
  • Tailscale
    • +
+
+
+

Timeouts

+
+ Setting timeouts is an important defensive measure for production environments, but must be tuned carefully to accommodate legitimate slow clients with large downloads or uploads. +
+
    +
  • Read timeout
    • +
  • Read HTTP header timeout
    • +
  • Write timeout
    • +
  • Idle timeout
    • +
  • TCP keepalive interval
    • +
+
+
+

Full duplex communication

+
+ Concurrent reading and writing of HTTP/1 is not supported by all clients, but can be enabled for certain clients and applications that require it. +
+
    +
  • Configurable for HTTP/1
    • +
  • Default for HTTP/2

    Request rewriting

    +
    + Rewriting is a different concern from proxying and is normally handled separately, but sometimes you need to rewrite requests using information from the proxy like the chosen upstream. Caddy's proxy lets you do this. +
    +
    +
    +

    Response interception

    +
    + By default, Caddy's proxy simply writes responses to the client. However, you can intercept the upstream's response and handle it in other ways. This includes matching only certain responses and invoking a custom handler chain you specify. +
