[cobalt-developers] Mod rewrite causing error 400?

["SarrCom.com - Reginald" <admin@xxxxxxxxxxx>]

Hi everyone,
On our Cobalt raq550 we use a virtual host with an inexistent domain name
'non-existant.com' to add a rewrite rule to access
folder/subfolder/subfolder through so called subdomains of another
virtualhost of an existing domain 'existing.com'.

example : http://www.existing.com/members/joh/john/  is accessible through
http://www.john.existing.com

Till yesterday we did all of this on a Cobalt raq4 without a problem but on the
raq5 we experience alot of 400 Bad Requests when accessing some of the
subdomains. When you refresh the browser, the page does get displayed.

Here are the vhosts files of the dummy and real domain.

[admin conf]$ cat vhosts/site1
# owned by VirtualHost
NameVirtualHost 80.x.x.3 (IP address)

# frontpage needs the following four things to be here
# otherwise all the vhosts need to go in httpd.conf, which could
# get very large since there could be thousands of vhosts

Does anyone have any idea what could cause these 400 errors???

How can we add this special rewrite rule to the real domain and keep the existing rewrite rule too?
