[HTTP-Recorder] Error in Logger.pm

[McMahon, Chris]

Hi... 
	I'm not certain why this happens, but it's easy to demonstrate: 
	Go to http://web.iihl.org. 
	At the bottom of the page, enter some search text. 
	Click the "Search" button.  
	Get several instance of this from the Proxy: 

Use of uninitialized value in concatenation (.) or string at
/usr/local/lib/perl5/site_perl/5.8.0/HTTP/Recorder/Logger.pm line 105.

	And the website returns an error page "under maintenance"
instead of correct search results.
