Cross platform reverse proxy with lighttpd

  • 772

I have a website www.somewebsite.com domain hosted on lighttpd 1.4 server configured with server.port = 8080 that is on a device (A) with local IP 192.168.1.26 and I want to get to use a reverse proxy in order to access another server that runs on a different device (B) at 192.168.1.30:80/myappin order to be accessed as

somewebsite.com/myapp

In device (A) server config I have enabled mod_proxy and I have tried to add

$HTTP["url"] =~ "^.*myapp" {
    proxy.server  = ( "" => 
        (( "(www.)?somewebsite.com" => "192.168.1.30", "port" => 80 ))
    )
}

but I get internal server error page when I try to access somewebsite.com/myapp

I have tried also

$HTTP["url"] =~ "(^/myapp/)" {   
  proxy.server  = ( "" => ("" => ( "(www.)?somewebsite.com" => "127.0.0.1", "port" => 8080 ))) 
}

$SERVER["socket"] == ":81" {   
  url.rewrite-once = ( "^/myapp/(.*)$" => "/$1" )   
  proxy.server  = ( "" => ( "" => ( "(www.)?somewebsite.com" => "192.168.1.30", "port" => 80 ))) 
}

but the result is even worse and server crashes completely

lighttpd reverse-proxy

    proxy.server do not take host as an argument, and "host" is a keyword, not a place to put your host here.

    Try this:

    $HTTP["host"] =~ "(www.)?somewebsite.com" {
 $HTTP["url"] =~ "^/myapp/" {
  url.rewrite-once = ("^/myapp/(.*)" => "/newapp/$1") # If you need to rewrite context.
  proxy.server  =  ( "" => ( "" => ("host" => "192.168.1.30", "port" => 80 )))
  }
}

  2. $HTTP["host"] =~ "(www.)?somewebsite.com" {
  $HTTP["url"] =~ "^/myapp/" {
    url.rewrite-once = ("^/myapp/(.*)" => "/newapp/$1")
  }
  $HTTP["url"] =~ "^/newapp/" {
    proxy.server  =  ( "" => ( "" => ("host" => "192.168.1.30", "port" => 80 )))
  }
}

    Alternatively, you can use proxy.header with "map-urlpath" with lighttpd 1.4.46 and later. See https://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModProxy
