Subject [users@httpd] problem using Apache with Zope
Date Sat, 12 Nov 2005 06:18:37 GMT

Dear People,

I'm having some problems with using Apache as a proxy with Zope/Plone.

I'm trying to get urls of the form




to redirect to my test Plone site at


via SSL.

However, I have not been successful.

I suspect this is an Apache misconfiguration, which is puzzling, since I 
have acess to a machine doing very similar things, also running Debian 
sarge, which is working.

I'll list misc. bits of info below, in the hope that this will help to 
narrow the problem. I'll also list the ssl config portion of my apache 
file at the bottom of this message for good measure.

This uses this thing called the Virtual Host Monster in Zope/Plone, which 
does some stuff enabling Virtual Hosts.

The core of the matter is the RewriteRule as follows.

RewriteRule ^/test_plone(.*) \{HTTP_HOST}:443/test_plone/VirtualHostRoot/_vh_test_\plone$1

1) Firstly, SSL is working, certificates are offered and accepted, yada 

2) I can acess the page at{HTTP_HOST}:443/test_plone/VirtualHostRoot/_vh_test_\plone$1


fine, where I have to replace with the IP address of the machine in 
question. This means the Virtual Host Monster is working correctly, I 

3) The rewriting is actually happening, because the rewriting log shows

client_ip_address - - [11/Nov/2005:18:51:56 --0500] 
[server_ip_address/sid#81565f0][rid#81ce540/initial] (2) init rewrite engine 
with requested uri /test_plone/colophon_xhtml.png
client_ip_address - - [11/Nov/2005:18:51:56 --0500] 
[server_ip_address/sid#81565f0][rid#81ce540/initial] (3) applying pattern 
'^/test_plone(.*)' to uri '/test_plone/colophon_xhtml.png'
client_ip_address - - [11/Nov/2005:18:51:56 --0500]

/test_plone/colophon_xhtml.png ->
client_ip_address - - [11/Nov/2005:18:51:56 --0500] 
[server_ip_address/sid#81565f0][rid#81ce540/initial] (2) forcing

[server_ip_address/sid#81565f0][rid#81ce540/initial] (1) go-ahead with proxy 


This all looks pretty normal.

4) The error log is cryptic. Setting LogLevel to debug does not seem to 
give any more usable information.

The main error is

[Fri Nov 11 18:51:56 2005] [error] [client client_ip_address] client denied by 
server configuration:

5) Here are the mods I have enabled.

/etc/apache2/mods-enabled# ls -la

drwxr-xr-x   3 root root 4096 2005-11-11 17:21 .
drwxr-xr-x  10 root root 4096 2005-11-11 15:45 ..

lrwxrwxrwx   1 root root   30 2005-11-11 17:19 rewrite.load -> 
lrwxrwxrwx   1 root root   26 2005-11-10 21:21 ssl.conf -> 
lrwxrwxrwx   1 root root   26 2005-11-10 21:21 ssl.load -> 
lrwxrwxrwx   1 root root   40 2005-11-10 16:52 userdir.conf -> 
lrwxrwxrwx   1 root root   40 2005-11-10 16:52 userdir.load -> 

These are included via the main config file.

6) I was wondering if there might be something wrong with the Proxy thing. I've 
kept proxy.conf at the Debian defaults. Included below.

In particular ProxyRequest are off, but another Debian machine I have access to 
works fine with that setting.

Thanks in advance for your help.
