Revproxy: Forward a request to another Web server

If you want to use this extension with Ocsigen Server's configuration file, have a look at the <<a_manual chapter="revproxy"|manual page>>. If you are using Ocsigen Server as a library, use the interface described here. Each of these functions behaves exactly as its configuration file counterpart.

This module belongs to ocamlfind package ocsigenserver.ext.revproxy.

Example of use. Forward all requests to a given directory to the same directory of another server running locally on another port. We are using it in combination with <<a_manual chapter="outputfilter"|Outputfilter>> to rewrite redirections.

let _ =
   Ocsigen_server.start
     [ Ocsigen_server.host ~regexp:".*"
       [ Revproxy.run
           ~redirection:(Revproxy.create_redirection 
                           ~full_url:false
                           ~regexp:"(othersite/.* )"
                           ~keephost:true
                           "https://localhost:8123/\\1") 
           ()
        ; Outputfilter.run 
            ~mode:(`Rewrite (Ocsigen_header.Name.location,
                             "http://localhost:8123/(.* )",
                             "http://my.publicaddress.org/\\1"))
            ()
 ]]

use Lwt_log.Section.set_level in order to set the log level

type redirection

val create_redirection : 
  ?full_url:bool ->
  ?pipeline:bool ->
  ?keephost:bool ->
  regexp:string ->
  string ->
  redirection

val run : redirection:redirection -> unit -> Ocsigen_server.instruction

run ~redirection () makes it possible to use this extension without configuration file.
