I have a configuration where I'm rewriting request to a %{DOCUMENT_ROOT}/break/break_on.html when %{DOCUMENT_ROOT}/break/break_on.enable file exists. Look at CONDITION NR1
DocumentRoot /opt/IBM/HTTPServer/htdocs RewriteEngine On
# CONDITION NR1
RewriteCond %{DOCUMENT_ROOT}/break/break_on.html -f
RewriteCond %{DOCUMENT_ROOT}/break/break_on.enable -f
RewriteCond %{SCRIPT_FILENAME} !break/break_on.html
RewriteRule (.*) /break/break_on.html [PT,L]
This was always working with traditional WebSphere. Now since I have WebSphere Liberty with dynamicRouting enabled, the dynamicRouting is sending a request to WebSphere Liberty Servers instead of rediricting it to local %{DOCUMENT_ROOT}/break/break_on.html

So it's obvious that I get 404, this resource doesn't exist on libertyNode, it exists where I have IBM HTTP Server installed.
How can I make sure, that all request are going to %{DOCUMENT_ROOT}/break/break_on.html when %{DOCUMENT_ROOT}/break/break_on.enable file exist on localhost instead of going to WebSphere Liberty Controller?
Thanks!
Since the URL shares a context root with a deployed application, you'll have to get the websphere plugin to decline handling it and let it defer to the default static file handler (very low priority):
The skipwas environment variable is the flexible way to handle this:
RewriteRule (.*) /break/break_on.html [PT,L,E=skipwas:1]
I don't think there's a tWAS vs Liberty difference here, or even dynamic routing. I think you were mapping your applications differently (or inadvertently have an application mapped to /)
