[users@httpd]
Hello,
I ve an Apache2.2+Tomcat5.5+Windows2K platform.
I use Apache2.2 to proxy almost all the requests for 80 port of my server
(http://www.mysite.it).
Since some days I would like to setup an Apache2.2 virtual host to show
the content of a site directly through Apache2.2 (i.e.: not proxying the
requests for the site - say http://www.virtualhost.it - to Tomcat).
It should be quite simple to set this up in httpd.conf:
# Virtual hosts
Include conf/extra/httpd-vhosts.conf
and in httpd-vhosts.conf:
<VirtualHost *:80>
ServerAdmin webmaster@mysite.it
DocumentRoot "C:/Apache2.2/htdocs/virtualhost2"
ServerName virtualhost.mysite.it
ErrorLog "logs/virtualhost.mysite.it-error_log"
CustomLog "logs/virtualhost.mysite.it-access_log" common
</VirtualHost>
But after reload apache service and I try to access to
http://www.virtualhost.it I get the content of http://www.mysite.it.
Basically it happens that the request for http://www.mysite.it is seen by
Apache as a request for / and so proxied to Tomcat.
How could I solve this issue?
Below I ve reported the mod_proxy configuration..
Thanks in advance,
rocsca

Difficult to say without having access to your /complete/ configuration,
and without looking at the access and error logs.
Arm yourself seriously for debugging, and don't make too many guesses
before you have some real data. Don't change too much at a time in your
configuration, or you will not know which is which anymore.
Start from a config that works, make one change and test.
Give each virtualhost section its own access log and error log.
If you use mod_rewrite, turn on its log too.
Then access your site once and look at the logs.
Access log tells you what it tried to access, and a code 200 if it was
ok, another code it was not.
The error log will tell you why it was not.
If you don't even get a line in the access log, it means that the
request did not even reach the server.
Use "nslookup" to verify that both your hostnames resolve to the same
IP, and that it is the IP of your server.
The first defined <VirtualHost> section acts as the default virtualhost,
so all calls where Apache cannot identify the target host will end up there.
If you need to see really what the server is sending in return to the
browser, get an appropriate plugin :
- HttpFox for Firefox
- Fiddler2 for IE
- .. ?

OK. Infact, I agree with you.. :-)
I really figure out why I don't see the content of document root specified
forthe virtual host.. :-( After all the access and errorlogs for the
specified virtual ho are created..
Any idea?

With respect, I think that this does not make sense.
Apache has to first parse the Host: header, before it even knows which
<VirtualHost> should handle the request. So it can certainly not apply
any specific VirtualHost section directive before it has read and
understood this header.
Think of another scenario to confirm/deny.

I forgot to mention the default virtual host just before the one above
that is sit in my virtual host conf file:
<VirtualHost *:80>
ServerName www.mysite.it
DocumentRoot "C:/Apache2.2/htdocs"
</VirtualHost>

Anyway I added the ServerAlias directive as well but nothing of good has
happened.. :-(
Please read what I report below again (I think that this is the key of the
mistake):
>> Basically it happens that the request for http://www.virtualhost.it is

So I think that the header Host: is considered after mod_proxy and so the
request is forwarded to Tomcat.
Could someone confirm this scenario?
thanks,
rocsca

[snip snip]
Please read http://httpd.apache.org/docs/2.2/vhosts/name-based.html
Basically you will need two virtual hosts listening to *:80. The first
one must have a ServerAlias www.mysite.it and the second one
virtualhost.mysite.it.
That should do the trick.
