 # :fontawesome-solid-handshake: HTTP
 
+## HTTP server
+
+kdb+ has an in-built service capable of handling HTTP/HTTPS requests.
+
+### Listening port
+
+When kdb+ is [configured](../basics/listening-port.md) to listen on a port, it uses the same port as that serving kdb+ IPC and websocket connections.
+
+### SSL/TLS
+
+HTTPS can be handled once kdb+ has been [configured to use SSL/TLS](ssl.md).
+
+### Authentication / Authorization
+
+Client requests can be authenticated/authorized using [.z.ac](../ref/dotz.md#zac-http-auth). 
+This allows kdb+ to be customized with a variety of mechanisms for securing HTTP requests  e.g. LDAP, OAuth2, OpenID Connect, etc.
+
+### Request handling
+
+HTTP request handling is customized by using the following callbacks:
+
+* [.z.ph](../ref/dotz.md#zph-http-get) for HTTP GET
+* [.z.pp](../ref/dotz.md##zpp-http-post) for HTTP POST
+* [.z.pm](../ref/dotz.md##zpp-http-post) for HTTP OPTIONS/PATCH/PUT/DELETE
+
+#### Default .z.ph handling
+
+The default implementation of .z.ph displays all variables and views. For example, starting kdb+ listening on port (`q -p 8080`) and visiting `http://localhost:8080` from a web browser on the same machine, displays all created variables/views).
+
+Providing q code as a GET param causes it to be evaluated eg. `http://localhost:8080?1+1` returns `2`. 
+
+[.h.HOME](../ref/doth.md#hhome-webserver-root) can be set to be the webserver root to serve files contained in the directory e.g.
+creating an HTML file index.html in directory `/webserver/` and setting `.h.HOME="/webserver"` allows the file to be viewed via  `http://localhost:8080/index.html'.

+### Keep-alive

+Persistent connections to supported clients can be enabled via [.h.ka](../ref/doth.md#hka-http-keepalive)
+
+### Compression
+
+HTTP server supports gzip compression via `Content-Encoding: gzip` for responses to `form?…`-style requests.
+The response payload must be 2,000+ chars and the client must indicate support via `Accept-Encoding: gzip` in the HTTP header.

 To use SSL/TLS, kdb+ should first be [configured to use SSL/TLS](ssl.md). For any request requiring SSL/TLS, replace `http` with `https`.
