# 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.
