Incoming&nbsp;-&nbsp;TrackBack
<p> TrackBack is a system devised by Ben and Mena Trott of <a href="http://www.movabletype.org" target="_blank">MovableType</a><br />
</p>
<h3>What is TrackBack?</h3>
<p>TrackBack allows blogs to talk. Suppose that you have been reading an interesting 
  post (Post A) on someone else's blog (Blog A). You may, after that, want to 
  write a post (Post B) on a similar theme on your blog. To let other people, 
  who may have read Post A on Blog A, know that you're thinking about the same 
  kind of thing and may have something to say that might interest them too you 
  can send a TrackBack ping from your blog to Blog A.</p>
<p>The ping contains information about your blog along with a short excerpt from 
  your post. Blog A will save the ping and display it along with Post A. Someone 
  reading Post A will then have an easy way to see that your Post B is on a similar 
  theme. Blog A will also provide a link to Post B on your blog for readers to 
  follow.</p>
<p>A TrackBack ping is sent to a specific URL connected to the post. Most blog 
  posts include &quot;meta data&quot; about the post that will enable you to find 
  the URL to send the ping too. This will either be a fragment of XML that BlogWorks 
  can pick up given the URL of the site or a line of text to the URL that you 
  cut 'n' paste into BlogWorks' TrackBack URL text box.</p>
<h3>BlogWorks <small>XML</small> and TrackBack</h3>
<p>BlogWorks implements practically all of the TrackBack specification. The only 
  part missing is the ability to query a BlogWorks blog's TrackBack system for 
  all pings to a certain post (normally returned as an RSS file). This feature 
  will be added once the BlogWorks API is finalised and built.</p>
<p>For finding TrackBack URLs BlogWorks has a pop-up window (icon: <img src="help/ic_trackback.gif" width="16" height="16">) 
  in which a site's URL can be entered. BlogWorks will then attempt to extract 
  all available TrackBack URLs from the page at the given URL. The process isn't 
  foolproof. Work is being done to up the &quot;hit rate&quot; for finding URLs 
  from a page. The main problem is that, despite TrackBack being a standardised 
  (and young) system, blog owners haven't always implemented the necessary XML 
  fragments that are required to automatically query TrackBack URLs - 'fraid that's 
  just how it is.</p>
<h3>Making it work</h3>
<p><b>Sending TrackBack pings:</b> simply enter the TrackBack URL of the post 
  you want to ping into the TrackBack URL text box on the New Post page. Multiple 
  URLs can be separated by commas.</p>
<p><b>Receiving TrackBack pings:</b> BlogWorks is ready &quot;out of the box&quot; 
  to receive TrackBack pings. However, for people to be able to ping your blog 
  you'll need to make all the relevant TrackBack information available through 
  your blog template.</p>
<p>Those using the default template supplied with BlogWorks (v1.1 onwards) will 
  have all this already set up ready to go but it doesn't hurt to know what's 
  going on...</p>
<p>TrackBacks are displayed in a pop-up window from themain blog (or archives) 
  page(s).<br>
  The tag <code>[rx:script]</code>in the &lt;head&gt; HTML tags of the template 
  will insert the required pop-up Javascript.</p>
<p>To reference the pop-up script and supply it with the PostID required by the 
  TrackBack display script use the following:<br>
  <code>&lt;a href="[rx:displayurl]" onClick="OpenWindow(this.href); return false"&gt;TrackBack&lt;/a&gt;</code> 
  between the <code>[+blog]</code> and <code>[-blog]</code> tags</p>
<p>The <code>[rx:displayurl]</code> tag supplies the URL to the display script 
  in the admin directory of the blog.<br>
  The <code>[rx:url]</code> tag can be used to show the TrackBack URL of the post.</p>
<p><b>Counting TrackBack pings:</b> it is possible to display the number of TrackBack 
  pings received by a post.<br>
  The <code>[rx:include]</code> tag in the &lt;head&gt; HTML tags of the template 
  will <code>#include</code> a file from the admin directory that contains a function 
  that counts those pings.<br>
  <i><b>Note:</b> at the moment this tag only works correctly if the admin_dir 
  directory is a subdirectory of the directory where main page and archive pages 
  are published.</i></p>
<p>To display ping counts: between the <code>[+blog]</code> and <code>[-blog]</code> 
  tags (preferably near the TrackBack link detailed above) add:<br>
  <code>&lt;%= rxCount("[postid]") %&gt;</code> </p>
<h3>Summary</h3>
<p><b>Displaying TrackBack pings received:</b><br>
  <code>[rx:script]</code>in the &lt;head&gt; tags of the template.<br>
  <code>&lt;a href="[rx:displayurl]" onClick="OpenWindow(this.href); return false"&gt;TrackBack&lt;/a&gt;</code> 
</p>
<p><b>Counting TrackBack Pings received:</b><br>
 <code>[rx:include]</code> in the &lt;head&gt; tags of the template.<br>
  <code>&lt;%= rxCount("[postid]") %&gt;</code> where the count is to appear.</p>
