/**
* Very simple web server.
*
* Serve local files in the docs/ directory, for CSS and images in
* error pages, using the reserved address proxy.i2p
* (similar to p.p in privoxy).
* This solves the problems with including links to the router console,
* as assuming the router console is at 127.0.0.1 leads to broken
* links if it isn't.
*
* Ignore all request headers (If-Modified-Since, etc.)
*
* There is basic protection here -
* FileUtil.readFile() prevents traversal above the base directory -
* but inproxy/gateway ops would be wise to block proxy.i2p to prevent
* exposing the docs/ directory or perhaps other issues through
* uncaught vulnerabilities.
* Restrict to the /themes/ directory for now.
*
* @param targetRequest decoded path only, non-null
* @param query raw (encoded), may be null
