how to create maintenance page with tuckey rewriting

[Rewriter]

Hello,

Would like to prepare a maintenance page for a tomcat webserver via tuckey rewriting rules.

How to convert this into a tuckey rewrite rule?

This is the general setup of an existing apache example i would like to use. 

RewriteEngine On

RewriteCond %{REMOTE_ADDR} !AAA.BBB.CCC.DDD

RewriteCond %{DOCUMENT_ROOT}/maintenance.html -f

RewriteCond %{DOCUMENT_ROOT}/maintenance.enable -f

RewriteCond %{SCRIPT_FILENAME} !maintenance.html

RewriteRule ^.*$ /maintenance.html [R=503,L]

ErrorDocument 503 /maintenance.html

What this does is...

turn on the rewrite engine

don't match your workstation or office IP address. (An exclusion so you can see the actual site, optional)

make sure the maintenance page exists

check for the .enable file. This is how you turn the holding page on and off. So that a service restart is not needed

don't apply the rule when serving the maintenance page (avoids circular rewrites)

Then the rule itself...

thanks Rewriter.
