Subject: [users@httpd] Reverse proxy with mod_rewrite using RewriteRule [P]

Hello:

We have two Apaches in a server:

Apache 2.2.14, reverse proxy, listening to IP 192.168.24.X
Apache 2.2.11, which actually serves the websites, listening to IP 
192.168.24.Y

Domain name proxy.mysite.es points to our reverse proxy Apache, and we 
need it to send requests to the other Apache in this way:

http://proxy.mysite.es/something -> http://something.mysite.es

Our rewrite rule:

RewriteRule ^/(.*) http://$1.mysite.es/ [L,P]

In RewriteLog we can see that the rewrite rule is working fine up to 
some point:

192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#eef078/initial] (2) init rewrite engine 
with requested uri /something
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#eef078/initial] (3) applying pattern 
'^/(.*)' to uri '/something'
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#eef078/initial] (2) rewrite '/something' 
-> 'http://something.mysite.es/'
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#eef078/initial] (2) forcing 
proxy-throughput with http://something.mysite.es/
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#eef078/initial] (1) go-ahead with proxy 
request proxy:http://something.mysite.es/ [OK]

Good, that is what we want, but it seems like something.mysite.es is not 
being sent to the Apache 2.2.11 but to the reverse proxy Apache itself, 
because the log follows:

192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#ef3088/initial] (2) init rewrite engine 
with requested uri /public/index.aspx
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#ef3088/initial] (3) applying pattern 
'^/(.*)' to uri '/public/index.aspx'
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#ef3088/initial] (2) rewrite 
'/public/index.aspx' -> 'http://public/index.aspx.mysite.es/'
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#ef3088/initial] (2) forcing 
proxy-throughput with http://public/index.aspx.mysite.es/
192.168.24.X - - [02/Mar/2010:15:46:19 +0100] 
[pre.mysite.es/sid#db73a0][rid#ef3088/initial] (1) go-ahead with proxy 
request proxy:http://public/index.aspx.mysite.es/ [OK]

Which of course leads to failure because of not being able to resolve 
domain name "public". A ping to something.mysite.es shows that it is 
being resolved to 192.168.24.Y, which is correct.

Any clue?

Thank you very much.

Daniel
