...Or with mod_lua at a 1/10th of the price of mod_rewrite if configured
properly :-)

# httpd.conf:
LuaMapToStorage /path/to/script.lua proxyhandler

-- script.lua:
function proxyhandler(r)
  r.handler  = "proxy-server"
  r.proxyreq = apache2.PROXYREQ_REVERSE -- or whatever you like.
  if r.headers_in['Upgrade'] == "WebSocket" then
     r.filename = "proxy:ws://backend:8080" ..r.uri
  else
     r.filename = "proxy:http://backend:8080" ..r.uri
  end
  return apache2.OK
end

With regards,
Daniel.

Hello All,

Couple of months passed since this question was answered
Are mod_rewrite/mod_lua still the only options to implement this? maybe
pod_proxy is now able to handle this?

Thanks in advance

works fine for me :)
What do you mean with "it's soo expensive" ?
Is rewrite less performant ?

The reason I didn't use proxy is that we use 'proxy' internally
and we now expose that via allowing its use as a handler...

Simply 'proxy'? Which would not be filenamed to "proxy:proxy:" but to
"proxy:${ap_http_scheme(r)}:"?
Otherwise, +1 for 'passthru'.

Re: [users@httpd] Preserve protocol in httpd proxy

Posted by Jim Jagielski <ji...@jaguNET.com>.

I have an idea which could be pretty simple to
implement and not add yet-another ProxyPass parameter.

A special scheme.

Ideally, something like

	ProxyPass / *://foo.example.com/

would be nice, with the special scheme '*' saying
"use the scheme of the request", but apr_uri_parse
barfs on that.

So how about 'passthru' as the special scheme? Or
maybe just 'pass', 'scheme' or even 'glob' ??

Have you tried the following?

RewriteEngine On
RewriteCond %{HTTP:Upgrade} =WebSocket [NC,NV]
RewriteRule ^/(.*) ws://my.backend:8080/$1 [P]
RewriteRule ^/(.*) http://my.backend:8080/$1 [P]
