Virtual server / redirection

[Ahgil12]

In apache, is it possible to set up virtual web server, then based on a host name with a context root and apache will direct the incoming request to an instance? For example,

Virtual host 1 for host/app1, which apache will direct all incoming request to

Http://localhost:80

Virtual host 2 for host/app2, which apache will direct all incoming request to

Http://localhost:82

If not possible to do, what is the way?

A reverse proxy may work for you.

http://docs.oseems.com/application/apache/configure-reverse-proxy

other than that, simply have a 0sec meta refresh

<meta http-equiv="refresh" content="0;url=http://www.hostname.com:82">

or with PHP

header('Location: [URL unfurl="true"]http://www.hostname.com:82')[/URL]

redirect on the directory index page.

Thanks for the quick reply.

Regarding the reverse-proxy, server has only 1 port open - 80. Then i want that one url (

http://host)

to have a root context, so:

http://host/app1

will direct requests to the app1 instance listening on port 81.

http://host/app2

will direct requests to the app2 instance listening on port 82.

How do I do this?

 

[ChrisHirst]

So if only port 80 is open, how are other services listening on 81 & 82?

Or do you mean that only port 80 is open through a firewall?

Another possible solution has sprung to mind, that of using frames.

Correct.

take a look at the Rewrite Rule this may be an option

So, the reverse proxy should work perfectly well, as the external request is made TO the HTTP port (80) but the content is being proxied from an internal IP and port.


Redirects and rewrites of course will not work in this case.

Can u please clarify how the proxy reverse work? I don't think the host name inside each virtual server can understand the host name plus the context root.

A proxy is aimply something that performs a service on your behalf. A reverse proxy is ... and referencing Wikipedia will save a whole lot of typing.

Correct, which is why you would normally use the internal IP and port of the server/machine you are proxying the content from, or for.

A HTTP request goes to

http://whatever/app/

the proxy then requests the output stream from nnn.nnn.nnn.nnnORT and spits it out via port 80.
