[Zope] Apache 2 and Zope Integration

[JohanNyberg at tsl.uu.se]

Hi Jim!

Thanks a lot for a very fast reply which solved the problem! There was
a small misprint in your mail: it should say p_ instead of _p. I also
had to add a RewriteRule for misc_ (there were errors in the apache error
saying:  File does not exist: /var/www/html/misc_). 

However, it seems to me your proposal is a somewhat brute force way of
solving the problem. Zope "should" add /zope/ to all URL:s it delivers,
but it does not. In any case, my problem is solved for the moment.

This is my current VirtualHost definition that works for me:

NameVirtualHost *
<VirtualHost *>
  ServerName myhost.mydomain
  <IfModule mod_rewrite.c>
    RewriteEngine On
    # use RewriteLog to debug problems with your rewrite rules
    # disable it after you found the error our your harddisk will be filled *very fast*
    #RewriteLog "/var/log/apache2/rewrite_log"
    #RewriteLogLevel 2
    RewriteRule ^/zope(.*) \
      http://localhost:9080/VirtualHostBase/http/%{SERVER_NAME}:80/VirtualHostRoot/_vh_zope/$1 [L,P]
    RewriteRule ^/manage(.*) \
      http://localhost:9080/VirtualHostBase/http/%{SERVER_NAME}:80/VirtualHostRoot/manage$1 [L,P]
    RewriteRule ^/p_(.*) \
      http://localhost:9080/VirtualHostBase/http/%{SERVER_NAME}:80/VirtualHostRoot/p_$1 [L,P]
    RewriteRule ^/misc_(.*) \
      http://localhost:9080/VirtualHostBase/http/%{SERVER_NAME}:80/VirtualHostRoot/misc_$1 [L,P]
    RewriteRule ^/(.*) - [L]
  </IfModule>
  <IfModule mod_proxy.c>
    ProxyVia On
    # prevent the webserver from beeing used as proxy
    <LocationMatch "^[^/]">
      Deny from all
    </LocationMatch>
  </IfModule>
</VirtualHost>

Thanks again for your help.

Johan
