      <h1>Wget Gateway</h1>
      <p>
	Welcome to Wget Gateway, a simple page showing the usage of
	socksified wget behind a firewall. In my configuration it is
	very useful because:
      <ul>
	<li>Only few users can exit from firewall
	<li>A lot of users need information that can be reached in Internet
	<li>I cannot dowload big files during my job time, so, I
	  have to schedule the requests after the normal work time
      </ul>

      <p>
	With the combination of a socksified wget and a simple cgi
	that schedules the requests can I reach the aim. All you need
	is:
      <ul>
	<li> A socksified copy of
	  <a href="ftp://gnjilux.cc.fer.hr/pub/unix/util/wget/wget.tar.gz">
	    wget</a>
	<li> Perl (available on all the GNU mirroring sites)
	<li> cgi-lib.pl (available at
	  <a href="ftp://ftp.switch.ch/mirror/CPAN/ROADMAP.html">CPAN</a>)
	<li> A customized copy of this html
	<li> A customized copy of socks.cgi
      </ul>
      This is my h/s configuration:
      <pre>

+----------+ +----------------------------------+ +---------------------+
| Firewall | | Host that can exit from firewall | | Intranet www server |
+----------+ |            htceff                | +---------------------+
             +----------------------------------+ | Wget.html           |
             | socksified wget                  | +---------------------+
	     | cgi-lib.pl                       | 
	     | perl                             |
	     | wget.cgi                         |
	     +----------------------------------+
      </pre>
      <p>
	wget.cgi, wget and cgi-lib.pl are located in the usual
	cgi-bin directory. The customization of wget.cgi and
	wget.html has to reflect you installation, i.e.:
      <ul>
	<li> download.html requires wget.cgi
	<li> wget.cgi requires Perl, cgi-lib.pl and wget
	<li>
	  wget.cgi has to download the files to a directory writable
	  by the user submitting the request.  At the moment I have an
	  anonymous ftp installed on <em>htceff</em>, and wget puts
	  dowloaded files to /pub/incoming directory (if you look at
	  wget.cgi, it sets the destdir to "/u/ftp/pub/incoming" if
	  the user leaves it blank).
      </ul>
      <p>
	You can also add other parameters that you want to pass to wget,
	but in this case you will also have to modify wget.cgi

      <hr>
      <form method="get" action="http://localhost/cgi-bin/wget.cgi">
	<h3>Downloading (optionally recursive)</h3>
	<ul>
	  <li>
	    Recursion:
	    <Select name=Recursion>
	      <Option selected value=N>No</Option>
	      <Option value=Y>Yes</Option>
	    </Select>
	  <li>
	    Depth:
	    <input type="radio" name=depth value=1 checked>1
	    <input type="radio" name=depth value=2 >2
	    <input type="radio" name=depth value=3 >3 
	    <input type="radio" name=depth value=4 >4
	    <input type="radio" name=depth value=5 >5
	  <li>
	    Url to download: <input name="url" size=50>
	  <li>
	    Destination directory: <input name="destdir" size=50>
	</ul>
	Now you can <input type="submit" value="download"> the
	requested URL or <input type="reset" value="reset"> the form.
