ROFLMAO !!!

I guess the previous code that i corrected after seeing Benjamin's
response:

==================
# determination of user browser
agent = agent.lower()
if 'chrome' in agent:
	agent = 'Chrome'
elif 'firefox' in agent:
	agent = 'Firefox'
elif 'opera' in agent:
	agent = 'Opera'
elif 'safari' in agent:
	agent = 'Safari'
elif 'msie' in agent:
	agent = 'Explorer'
else:
	agent = 'Other'
====================

would still be failing since it seems that it is a matter of order
what response will be presented.

So if you use firefox for browser with the UA string tweaker on with a
string of "Chrome Firefox
MSIE Opera Safari Mozilla Lynx Links Dillo Win32 Windows Linux OpenBSD
Mac OS X" and browse my site the result will always be 'Chrome'
since the 1st match will always be TRUE and nothing else get
checked. :-)

But in a real example if a UA string contains the substring 'Chrome'
then the browser must be Chrome(there is no point containing the
substring 'Firefox' in UA when the browser is 'Chrome', unlike Mozilla
which is a common subtring to both of the browsers UA)
