404 error in a particular automatic subdomain system

[Teschio]

Hi to all, I have this code in my httpd.conf where:
if i digit www.everything.domain2.com (also without the www prefix) i'm redirected to internal domain1 path of www.domain1.com/everything....
Id like to do this redirect only if "everything" folder exist under www.domain1.com... if it does not exist i'd like to receive a custumed 404 error page...
I tried adding "ErrorDocument 404 /error.php" on my code but it doesn't work (for it no subdir exists)!
How can I do?
This is the code I have:

<VirtualHost www.domain2.com>
ServerName www.domain2.com
ServerAlias domain2.com *.domain2.com
DocumentRoot /home/web/www.domain1.com/website
ErrorDocument 404 /error.php
RewriteEngine on
#my fixed subdomain
RewriteCond %{HTTP_HOST} ^(www\.)?forum\.domain2\.com
RewriteRule (.*) [forum.domain1.com$1...] [R=301,L]
#Redirect 4 domain2.com
RewriteCond %{HTTP_HOST} ^(www\.)?domain2\.com
RewriteRule (.*) [domain1.com$1...] [R=301,L]
RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain2\.com
RewriteRule (.*) /%2$1 [L]
</VirtualHost>

Thank you.

You'll need to use RewriteCond to test for "directory exists." I'll get you started with an example that might work, but you're probably going to have to adapt this to your particular server and needs, and then test it.

RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain2\.com
RewriteCond %{DOCUMENT_ROOT}/%2 -d
RewriteRule (.*) /%2$1 [L]

Excuse me... now i have:

<VirtualHost www.domain2.com>
ServerName www.domain2.com
ServerAlias domain2.com *.domain2.com
DocumentRoot /home/web/www.domain1.com/website
ErrorDocument 404 /error.php
RewriteEngine on
#my fixed subdomain
RewriteCond %{HTTP_HOST} ^(www\.)?forum\.domain2\.com
RewriteRule (.*) [forum.domain1.com$1...] [R=301,L]
#Redirect 4 domain2.com
RewriteCond %{HTTP_HOST} ^(www\.)?domain2\.com
RewriteRule (.*) [domain1.com$1...] [R=301,L]
RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain2\.com
RewriteCond %{DOCUMENT_ROOT}/%2 -d
RewriteRule (.*) /%2$1 [L]
RewriteCond %{REQUEST_FILENAME}!-d
RewriteRule (.*) /error.php [L]
</VirtualHost>

and it works... if www.blah.domain2.com does not exist i have the error page...
But I'd like also that if i digit www.existent_subdomain.domain2.com/non_existent_file_or_directory i get an error page... also error2.php is good...

Which modification do i have to make?
Thanks

Please excuse me again...
I think after your explanation it was easy for me to make the code... but now i'm sure it's a "mission impossible" for my brain!
There are 3 error pages i have to manage...

1)I digit www.non_existent_subdomain.domain2.com ---> will get error_1.php
1a)I digit www.non_existent_subdomain.domain2.com/non_existent_dir_or_file ---> will get error_1.php

2)I digit www.existent_subdomain.domain2.com/non_existent_dir_or_file ---> will get error_2.php

3)I digit www.domain1.com/non_existent_dir_or_file ---> will get error_3.php

The complete code i have in my httpd.conf is this:

<VirtualHost www.domain1.com>
ServerName www.domain1.com
ServerAlias domain1.com *.domain1.com
DocumentRoot /home/web/www.domain1.com/website
RewriteEngine on
#my fixed subdomain
RewriteCond %{HTTP_HOST} ^forum\.domain1\.com
RewriteRule (.*) /home/web/www.domain1.com/website/forum/$1 [L]
RewriteCond %{HTTP_HOST} ^www\.forum\.domain1\.com
RewriteRule (.*) [forum.domain1.com$1...] [R=301,L]
#Redirect 4 domain1.com
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST}!^(www¦forum)\.domain1\.com
RewriteRule (.*) [domain1.com$1...] [R=301,L]
</VirtualHost>

<VirtualHost www.domain2.com>
ServerName www.domain2.com
ServerAlias domain2.com *.domain2.com
DocumentRoot /home/web/www.domain1.com/website
RewriteEngine on
#my fixed subdomain
RewriteCond %{HTTP_HOST} ^(www\.)?forum\.domain2\.com
RewriteRule (.*) [forum.domain1.com$1...] [R=301,L]
#Redirect 4 domain2.com
RewriteCond %{HTTP_HOST} ^(www\.)?domain2\.com
RewriteRule (.*) [domain1.com$1...] [R=301,L]
RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain2\.com
RewriteCond %{DOCUMENT_ROOT}/%2 -d
RewriteRule (.*) /%2$1 [L]
RewriteCond %{REQUEST_FILENAME}!-d
RewriteRule (.*) /error_1.php [L]
</VirtualHost>

Really Thanks!
