Setting-up an Automatic Ping for RSS

[brett7481]

I've been fooling around with this, but can't quite seem to get it.

How do I set-up an automatic ping? I've tried examples like this:

POST / HTTP/1.0
Host: ping.blo.gs
Content-Type: text/xml
Content-Length: 394

<?xml version="1.0" encoding="iso-8859-1"?>
<methodCall>
<methodName>weblogUpdates.extendedPing</methodName>
<params>
<param>
<value>I ♥ São Paulo</value>
</param>
<param>
<value>http://ilovesaopaulo.example.com/</value>
</param>
<param>
<value></value>
</param>
<param>
<value>http://ilovesaopaulo.example.com/index.rss</value>
</param>
</params>
</methodCall>

I've saved that at auto_ping.xml... but that doesn't seem to work.

Should I be saving it else where or as a different extension? Should it go within my actual RSS Feed?

Thanks in advance.
