The reverse proxy doesn't appear to be working. My block now looks like
the following:
ServerAdmin administrator@xxxxxxxxxxxx
ServerName www.domain.co.uk
DocumentRoot /var/www/html/domain
ProxyRequests off
ProxyPass /folder http://virtualfolder/
ProxyPassReverse /folder http://virtualfolder/
I've also got the line:
LoadModule proxy_module modules/mod_proxy.so
I've confirmed the file is under the modules directory.
I restarted Apache using apachectl graceful.
Requests going to http://www.domain.co.uk/folder get the message:
Object not found!
The requested URL was not found on this server. If you entered the URL
manually please check your spelling and try again.
If you think this is a server error, please contact the webmaster.
Error 404
www.domain.co.uk
Apache/2.0.59 (Unix)
While I can understand not getting the reverse proxy right straight off
the bat, this looks like it isn't redirecting at all. Where am I going
wrong?
error_log just registers the following:
[Tue Nov 27 15:41:08 2007] [error] [client 1.1.1.1] File does not exist:
/var/www/html/domain/folder
[Tue Nov 27 15:41:12 2007] [error] [client 1.1.1.1] File does not exist:

/var/www/html/domain/folder

Hi all, first time on the apache list so have mercy ;)
I have been tasked with setting up a system whereby a Linux
server
running apache 2.0.59 in the DMZ takes requests on port 80 and
then
passes them through to an internal Windows server running IIS
which
actually hosts the HTML.
Such a setup already exists (though it's Linux to Linux) so I
thought
this would be relatively easy to do, just copy the existing
setup.
People currently connect to
http://www.domain.co.uk/folder/login.html
and all is well. Searching the httpd.conf file I can find only
one
reference to folder, which is:
<VirtualHost *:80>
ServerAdmin administrator@xxxxxxxxxxxx
ServerName www.domain.co.uk
DocumentRoot /var/www/html/domain
RewriteEngine on
RewriteRule ^/folder(.+)
https://www.domain.co.uk/folder$1 [R,L]
RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
RewriteRule .* - [F]
</VirtualHost>
So we're using the rewrite module... except having read the
documentation on this feature I cannot fathom it.
I hoped that with the above I could simply add another line:
RewriteRule ^/folder2(.+) https://www.domain.co.uk/folder2$1
[R,L]
I then added a route for the relevant server so the traffic is
routed to
the internal network when its name is called. However, without
really
understanding the above I'm not in much of a position to
progress
further when this invariably fails to work. I don't know whether
the
above in any way relates to the name apache calls which then
causes the
call to be routed to server X.
Any advice or guidance you can offer would be much appreciated.

Your example is not rewriting to an internal server. You want to use
mod_proxy. Let's say your windows box is 192.168.1.100, then you want
something like this inside your VirtualHost directive:
ProxyRequests off
ProxyPass /folder2 http://192.168.1.100
ProxyPassReverse /folder2 http://192.168.1.100
With this, anytime someone visits your externally accessible site at
http://www.domain.co.uk/folder2, they'll see the html output by your
windows server at http://192.168.1.100 and your internal IIS host is
never directly accessible from the internet.
cheers,
