Example 6 with NamingService

use of net.i2p.client.naming.NamingService in project i2p.i2p by i2p.

the class LocalHTTPServer method serveLocalFile.

/**
 *  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
