Apache Friends Support Forum

I've got XAMPP running on port 80, and a web app on port 8000. I need a rewrite rule so that requests coming in on port 80 are sent to the web app on port 8000, without the browser noticing.

It seems like a fairly simple and obvious thing to do, but I simply cannot figure it out. Usually I get some kind of error message (400 Bad Request, 500 Server Error). The best attempt gave a browser redirect, which isn't what I need, but I figured adding a [P] or maybe [PT] flag would do it, but that resulted in an error.

So what's the correct way to do this?

What you need to configure is a so called "Reverse Proxy". You cannot solve your problem with a Rewrite, as you redirect to a different server and this is evaluated by the browser.

But I don't want it evaluated by the browser. I want the browser to talk just to Apache, and Apache to hand the request to my app.

I guess I'm going to need something like:

Code: Select all

ProxyPass ^(.*) http://localhost:8000{REQUEST_URI}
ProxyPassReverse ^{.*}http://localhost:8000{REQUEST_URI}

Or maybe just

Code: Select all

ProxyPass /app(.*) http://localhost:8000/app$1
ProxyPassReverse /app(.*) http://localhost:8000/app$1

Although the mod_proxy page sounds like [P] should also work:

A reverse proxy is activated using the ProxyPass directive or the [P] flag to the RewriteRule directive.

As i wrote above. But this is an ugly ProxyPass.

Yes, but you dont need a rewrite, you need a ReverseProxy Only. The easies and best way of creating a working ProxyPass is a VirtualHost with a ProxyPass (so you can pass all Requests to the ReverseProxy). Create any Subdomainname and create a VirtualHost:

Code: Select all

<VirtualHost *:80>
Servername OtherApp
ProxyPass / http://localhost:8000/
ProxyPassReverse / http://localhost:8000/
</VirtualHost>

And if you enter http://OtherApp into your Browser, it will show the contents of localhost:8000

Thanks! That looks exactly like what I need.
