Wildcard vhost with modperl - apache2

I have a server on which I want to run multiple wildcard vhosts, with their own modperl environment.
Each vhost needs to run it's own startup script to define custom include paths.
In a normal vhost configuration, I can do the following...
<VirtualHost *:80>
ServerName web1.myserver.com
Define ApplicationRoot /websites/web1
DocumentRoot ${ApplicationRoot}
PerlSetEnv PERL_DOC_ROOT ${ApplicationRoot}
PerlOptions +Parent
PerlPostConfigRequire /websites/lib/startup.pl
...
My startup.pl script can then use the PERL_DOC_ROOT environment variable to dynamically configure custom lib paths.
This works fine with multiple vhosts sections. They each have their own #INC defined, and everything resolves correctly.
Is there some way I can translate this to a wildcard vhost configuration. I'd like users to be able to access *.myserver.com, and it will use the hostname to figure out which documentroot to use, and will run the startup.pl to define lib paths based on this folder.
I know I can use something like this...
VirtualDocumentRoot /websites/%1/
to dynamically set the document root, but if I try to use %1 in any other declarations it is not understood. Also the startup.pl would need to run when the site is first requested, rather than when the config file is first loaded.
Is this possible at all? Or would I need to somehow dynamically rewrite the config files each time a new virtual directory is added.

I realised I'm overcomplicating it. I don't need to use wildcard vhosts. Since I'll be using Jenkins to create the vhosts directories, I can also get it to dynamically create config files to match.

Drupal 7 - Views.css and CTools.css not loaded

When using the Views admin panel, it appears completely mispresented. Looking at the files being accessed, it turns out that the needed css files are not loaded. My Drupal installation is within a /drupal/ subfolder, and when the module is trying to access domain.com/sites/all/modules/views/css/views.css a 404 is received.
I tried browsing manually to domain.com/drupal/sites/all/modules/views/css/views.css and it works, therefore the file is there and can be accessed from the web.
The strange thing is that for other folders there is no problem, for example both domain.com/modules/user/user.css and domain.com/drupal/modules/user/user.css work. It seems like a problem with sites/ only...
I do not have CSS optimization enabled, and all folders within sites/ have a 755 permission. Is there some configuration setting I'm missing?
Apparently, the domain I'm concerned about is a parked domain (or whatever this is called) for another one, and contained in a subfolder of public_html. Drupal installation, thus, is a subfolder of that subfolder (say, /home/user/public_html/my_domain/drupal) and all requests for my domain are redirected via an .htaccess and MOD_REWRITE, to the Drupal subfolder. For some reason, it didn't have the sites/ in its regexp (modules/ and themes/ were...).
You may have incorrect vhost configuration. In order to check if this is the reason, try accessing the site without the vhost i.e. localhost/drupal and see if this works.
If it loads correctly, then you need to set up the correct document root:
<VirtualHost *:80>
DocumentRoot /www/drupal
ServerName domain.com
</VirtualHost>
Then restart apache.

Can't get Apache directory indexing to stop

I am trying to get my OSX MacPorts install of Apache to NOT show directory listings. I have tried various configurations of the "options" directive in the httpd.conf file with no luck. When I go to the site, it still lists the root directory (there is no index file at the moment.)
Apache has been restarted after each change.
There is no .htaccess file in the / directory, so there shouldn't be anything overriding.
This is driving me crazy!
So basically something is overriding your config. From the documentation of apache we can read that Options is can be placed in various context: server config, virtual host, directory, .htaccess.
httpd.conf is read first, so if You provided the configuration properly there, it means that it is overridden somewhere else
How did You do enter the options in the config ? In the most basic variant it should be.
<Directory /path>
Options -Indexes
</Directory>
Here what you should do:
check module configurations in modules for Options Indexes
check the main virtualhost definition, probably called default or 000-default
If it still does not help, add Options -Indexes to your virtualhost directly (provided you have not done it already). Or add it to the .htaccess file in your directory (allowing Options in .htaccess needs to be switched on)[as suggested in comments]

how load Module rewrite without accessing to httpd.conf

i am using cakephp and i need load Module rewrite , but i can not accessing to httpd.conf.
there is way to solve this problem ?
by thanks.
Its not a possibility if you do not have access to conf files.
Modules have to be loaded when Apache start. Nothing cam be done WRT this after Apache has started.
mod_so is used to load modules. Although DSO(Dynamic Shared Object) is used, a restart to the server is required.
from Dynamic Shared Object (DSO) Support:
The DSO support for loading individual Apache modules is based on a module named mod_so which must be statically compiled into the Apache core. It is the only module besides core which cannot be put into a DSO itself. Practically all other distributed Apache modules can then be placed into a DSO by individually enabling the DSO build for them via configure's --enable-module=shared option as discussed in the install documentation. After a module is compiled into a DSO named mod_foo.so you can use mod_so's LoadModule command in your httpd.conf file to load this module at server startup or restart.
If your host has enabled it, you can place an .htaccess file in your CakePHP directory. Its contents must be the same as the ones you would want to write into the httpd.conf file. An example might be:
<IfModule mod_rewrite.c>
RewriteEngine On
# Add your rewrite rules here
RewriteRule ^/somepage$ somepage.php
</IfModule>

why does apache forbid access via symbolic links?

I am trying to install typo3 as per the instructions but I have a bit of a puzzle to solve.
It seems apache denies access to any files I try to access via any symbolic link in the site root directory. I have changed permissions from SymLinksIfOwnerMatch to FollowSymLinks and no joy.
I'm working on mac OSX (SL) and installing in my user's "Sites" directory. I can access any files in this CMS directory via the web browser just not anything through symbolic links.
I hope konsolenfreddy's comment was helpful already. I am trying to round things up here:
First check if the symlinks work from terminal and/or the filesystem in general.
Also, if you use absolute paths, the whole path from root to the file in question must be readable by the Apache user. *
If yes, check if the AllowOverride option is set for your webserver (or if applyable for the virtual host) For debugging you can set AllowOverride All in either apache2.conf, httpd.conf or in sites-available/default
If yes, check if FollowSymlinks is aktivated in any of the files responsible for your webroot, starting with apache2 working yourself down to the .htaccess files.
Try changing file permissions on the symlink file and the target directory (or files)
Try creating your own symlink and see what happens when you call it in the browser.
* Check this answer at askubuntu.com for more hints.
Ok I eventually solved it. In OSX the final file that governs access of sites installed in user directories is the last Include line in the apache2/conf/extra/httpd-userdir.conffile. Once I changed that my problems went away.
Thanks to all the people that replied my questions.

Can I use an environment variable like hostname from the shell in httpd.conf?

I am trying to have all my webservers write their logs to a shared storage system. I'd like to use a system environment variable so that I don't have to maintain 20+ httpd.conf files. My httpd.conf files are part of my deployment, we do this so that if we need to change something all hosts get that change.
What I'd like to do is something like this:
ErrorLog "|/usr/local/apache2/bin/rotatelogs /data/logs/apache/${hostname}_error_log.%Y-%m-%d 86400"
where hostname is the same thing returned by the shell command, eg:
user#server1.domain#01:47:17:~ $> hostname
server1.domain
I noticed that because I am using the | through to rotatelogs I should try $HOSTNAME and whuduya know.
ErrorLog "|/usr/local/apache2/bin/rotatelogs /data/logs/apache/$HOSTNAME.error_log.%Y-%m-%d 86400"
works great :)
