Apache mod_rewrite and multiple domains
I'm trying to use mod_rewrite to map multiple domains to different servlets on one开发者_JS百科 host. Example:
www.dom1.com -> 192.168.1.n/dom1
www.dom2.com -> 192.168.1.n/dom2 ...
I'm using the mod_rewrite and mod_proxy and VirtualHost directive but it seems that the reverse mapping via ProxyPassReverse doesn't work as I expected.
ProxyPassReverse /subdomain.domain.com http://192.168.1.n/subdomain
doesn't work. I've turned rewrite-logging on with
RewriteLog /var/log/rewrite.log
From the logs I'd say that rewriting works and the problem seems to be with reverse mapping. However I can't see any Reverse mapping entries. It seems that reverse mapping isn't logged or needs a different command to be activated. (Apache and the servlet container are on different machines but this should not matter I'd think ?)
After all I've found a solution that works for me. This is an excerpt from my configuration that shows one virtual host for domain 1
<VirtualHost *>
ServerName www.dom1.com
ServerAlias dom1.com
RewriteEngine On
# logs might be omitted
RewriteLog /var/log/dom1_rewrite.log
RewriteLogLevel 2
CustomLog /var/log/dom1_custom.log common
ErrorLog /var/log/dom1_error.log
# rewrite to internal ip
RewriteRule ^/(.*) http://192.168.1.105/dom1/$1 [L,P,E=proxy_ok:1]
# Preserve the host-part in the forwarded url
ProxyPreserveHost On
# Substitute responses with the original
ProxyPassReverse / http://192.168.1.105/dom1/
ProxyPassReverse / http://192.168.1.105/dom1
ProxyPassReverse / http://dom1.com/dom1/
ProxyPassReverse / http://dom1.com/dom1
</VirtualHost>
What was wrong with my first configuration - I had to preserve the host and then add all necessary ProxyPassReverse rules to substitute the responses.
And this is my mod_proxy configuration:
<IfModule mod_proxy.c>
#turning ProxyRequests on and allowing proxying from all may allow
#spammers to use your proxy to send email.
ProxyRequests Off
<Proxy *>
AddDefaultCharset off
Order deny,allow
Deny from all
# Proxies just in case Proxy_ok is set
Allow from env=proxy_ok
</Proxy>
# Not sure whether we need this ...
# Enable/disable the handling of HTTP/1.1 "Via:" headers.
# ("Full" adds the server version; "Block" removes all outgoing Via: headers)
# Set to one of: Off | On | Full | Block
ProxyVia On
</IfModule>
There may be cleaner solutions but - if works as it should.
