TracMultipleProjectsWindows - 3rd RewriteRule not reached?

[Ming]

On TracMultipleProjectsWindows :

RewriteRule ^/projects/+$			/projects/index.html [L]
#RewriteCond /var/lib/trac/$1			-d   
# following rule check TRAC_ENV, after $1 you may need to add '.db' if based on Trac install
RewriteRule ^/projects/([[:alnum:]]+)(/?.*)	/projects/trac.cgi$2 [S=1,E=TRAC_ENV:c:/svn/$1]
RewriteRule ^/projects/(.*)			/projects/index.html

1st rule successfully redirects http://<hostname>/projects -> http://<hostname>/projects/index.html
2nd rule successfully redirects existing projects to http://<hostname>/projects/<projectname>
3rd rule can't seem to catch non-existing projects?
Thanks!

Is there some reason this can't be done with TRAC_ENV_PARENT_DIR? If there isn't I would propose to close as wontfix.

No follow-up, closing.
