rewrite to hidden url. customer should not see the following URL which should be called.
http://www.x.com/myapp/
and add following parameters
language=en
customerID=3
I am trying this rule but get always 404 http status error
<rule match-type="regex">
<from>^/customer1/en/([A-Za-z0-9\._/]+)$</from>
<set name="customerID">3</set>
<set name="language">en</set>
<to type="forward">/myapp/$1</to>
</rule>

I assume you have one webapp with context-root = "/" (no cross-context).
Maybe you should activate the logs if it's not done, and see if your rule is called and matched.
You can activate log for urlrewritefilter in the filter config (see http://urlrewritefilter.googlecode.com/svn/trunk/src/doc/manual/4.0/index.html#filterparams).
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
<!-- sets up log level (will be logged to context log)
can be: slf4j, TRACE, DEBUG, INFO (default), WARN, ERROR, FATAL,
sysout:{level} (ie, sysout:DEBUG)
if you are having trouble using normal levels use sysout:DEBUG
(default WARN) -->
<init-param>
<param-name>logLevel</param-name>
<param-value>DEBUG</param-value>
</init-param>
</filter>
You must also add the dependencies for the logging, like slf4j-api, slf4j-log4j12, log4j-1.2.
