If you try to run a local version of WordPress against a live database, you will be redirected to the live URL. The reason for this is that the URL is defined in the database (wp_options table). In order to work around this, you can add the local URL to the /wp-config.php file:

define('WP_SITEURL', 'http://localhost:81');
define('WP_HOME', 'http://localhost:81');

If you try to trace your web applications using Fiddler with default settings under Windows 7, you will get the following error in your browser:

[Fiddler] Connection to localhost. failed.
Exception Text: No connection could be made because the target machine actively refused it ::1:80

This can be fixed by disabling IPv6 in Fiddler:

1. Go to Fiddler, then Tools > Fiddler Options.
2. Uncheck "Enable IPv6 (if available)".

Tracing should now work.

Fiddler is a great tool for tracing the HTTP traffic for your web applications. However, if you try to trace http://localhost/ you will see that it does not work. This can be fixed by either using the machine name or adding a dot at the end of the localhost address:

http://mycomputername/

or

http://localhost./
