Every web server has the ability to specify the user -- say, nobody or www_user -- that the server will run as. It uses high privilege to open the low-numbered ports, then immediately (and, irrevocably) becomes a non-privileged user. It's a one-way street, they can't go back. Furthermore: if you are using FastCGI, the worker processes never need to have high privilege, nor necessarily the same user-ids.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
