Rewriting URL 1 to URL 2 with timestamp / random number

[doe...@aekwl.de]

Hi guys,

I have the following task, but no idea how to deal with UrlRewrite in Tomcat.

URL input: https://server.test.de

URL output: https://12345.server.test.de

The prefix before .server could be a timestamp or a unique random number.

Could you please give me a hint to write the rule, if it's possible?

Thanks!

Andre
