2 websites, same content

[hotpurple]

Hi,

I'm quite new to apache, but I administrate an application that uses apache to create a web based UI.

Internally the website uses the server's fully qualified machine name eg hostname1.domain1.com/webapp

I'm trying to set the application to be accessable by anyone with an internet connection, external to the company, that is move the app from the local intranet to be accessable from the internet, but still allow the old intranet address to be accessible internally.

As a result I need to be able to rewrite all the links the application produces, which are created dynamically (so I am lead to believe). I believe I need to use a combination of mod_rewrite and virtual hosts, I'm just not sure how to set this up.

What I want to do is setup a server that answers to both:

http://hostname1.domain1.com/webapp
and
http://hostname1.domain2.co.uk/webapp

and for all the urls to be rewitten on the fly to link to the domain2.co.uk address.

Can anyone suggest how I do this please?

Many Thanks

Chris

Itd be much easier to rewrite it to use relative rather than absolute paths (i.e ../blah) to go one directory up and into the folder blah than rewrite the entire thing based on the incoming ip (which would prob be the easiest test for internal or external)

Thanks for the speedy reply,

Unfortunately I can't do that, as the web based application creates it's links dynamically, based on some processes that run in the background (it's a data management solution that uses a web page as it's ui). The domain was specified during the installation of the system and I am now unable to change it without delving deep into the code that runs the system, which I am loath to do. Is there not a way to use mod_rewrite to just change the URL?

Cheers

Perhaps you could just open another port for Apache, tell it to go to the same place as the existing site (or a symlink to it), and do some DNS voodoo to get external hits to go to the new port?

For mod_rewrite, I'm not sure it can change the actual domain name, but I could be wrong. These are as good as any places to start:

http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html
http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html

Edit: Ooo, this looks interesting (from the 2.0 doc):

^/somepath(.*) http://otherhost/otherpath$1 http://otherhost/otherpath/pathinfo via external redirection
