URL_LFS_REWRITE(8)

NAME
 url_lfs_rewrite - a URL-rewriter based on local file existence

SYNOPSIS
 url_lfs_rewrite [--debug] --local-dir=/var/www/ [options]

DESCRIPTION
Direct all request to files who are in a local directory to a local web server hosting this directory.

This program uses Squid concurrency support.

OPTIONS

--debug
    Write debug info to stderr.

--local-dir
    Directory path under which the scripts searches for files.

--to-scheme
    Scheme to use for the redirected URL.

     Default: http

--to-host
    Domain name to use for the redirected URL.

     Default: localhost

--to-path
    URL path to add as prefix for the redirected URL path.

    If set it must end with a '/'.

     Default: use the original URL path.

KNOWN ISSUES
* The --local-dir parameter must end with a '/'. Otherwise no
  file paths will be found.

* URL with no filename in the path can match directories on the local
  filesystem and be wrongly redirected to the local web server.

* Any scheme name accepted by the Perl URL library can be used
  as the --to-scheme parameter. However only schemes supported by
  Squid will work.

* URL containing query-string are not handled well and will not
  be rewritten even if the base script or file exists on the local
  system.

CONFIGURATION
  url_rewrite_program /path/to/url_lfs_rewrite --local-dir=\var\www\localhost
  url_rewrite_children 20 startup=1 idle=1 concurrency=25
  url_rewrite_access deny CONNECT
  url_rewrite_access deny to_localhost

This helper can redirect to any web server but only does so if there is a file matching the URL path segment in the local filesystem. Normal configuration requires a web server running on localhost serving up files from a local disk (eg. \var\www\localhost). Configuration of that web server is not covered here.
